SharePoint Server 中的搜尋結果排名概觀Overview of search result ranking in SharePoint Server

摘要: 了解 SharePoint Server 2016 和 SharePoint Server 2013 如何使用排名模式計算搜尋結果的相關排名,以及如何使用查詢規則、搜尋結構描述和排名模型影響搜尋結果的順序。Summary: Learn howSharePoint Server 2016 and SharePoint Server 2013 use ranking models to calculate the relevance rank of search results and how you can influence the order of search results by using query rules, the search schema and ranking models.

搜尋引擎將計算相關排名,也就是查詢的搜尋結果出現的順序。排名模型是這個計算的核心。在大多數情況下,您可以使用可用的 SharePoint Server 排名模型與查詢規則影響相關性,完全不需要考慮自訂任何排名模型。The search engine calculates the relevance rank, that is to say, the order in which the search results for a query appear. The ranking model is at the core of this calculation. In most cases, you can influence relevance by using the available SharePoint Server ranking models in combination with query rules without having to consider customizing any ranking models.

什麼是排名模型?What is a ranking model?

SharePoint Server 有幾個排名模型適用於特定情況。這些排名模型提供結果的有效排名,完全不需要其他任何自訂。排名模型包含一組排名功能,可計算特定項目的排名分數,例如搜尋結果中的文件。排名的內容類型將決定排名模型使用的排名功能,以及這些不同的排名功能使用的相關重要性。There are several ranking models in SharePoint Server that are optimized for specific cases. These ranking models provide an effective ranking of results without any further customization. A ranking model contains a collection of ranking features to calculate the rank score of a particular item, for example a document, in the search results. The type of content that is ranked determines the set of ranking features that the ranking model uses and the relative importance of these different ranking features.

對於預設搜尋類別 [所有項目]*、[影片]、[交談]*** 及 [人員]*,搜尋系統將自動使用最適合的排名模型。如果您自行建立搜尋類別,則可設定對於該類別使用的排名模型。, , and For the default search verticals *Everything, Videos, Conversations and People, the search system uses the most appropriate ranking model automatically. If you create your own search vertical, you can configure which ranking model to use for that vertical.

SharePoint Server 提供下列類型的排名模型:SharePoint Server provides the following types of ranking models:

  • 一般用途排名模型。General purpose ranking models.

    一般用途排名模型可計算大多數搜尋結果類型的相關排名。General purpose ranking models compute the relevance rank for most types of search results.

  • 人員搜尋排名模型。People search ranking models.

    人員搜尋排名模型可計算人員相關搜尋結果的相關排名。另外,也會根據關係距離和專業計算相關搜尋結果。按照People search ranking models compute the relevance rank for search results that are related to people. They calculate, among other things, how relevant search results are based on social distance and expertise.

  • 特殊用途排名模型。Special purpose ranking models.

    特殊用途排名模型可計算各種特定排名情形相關搜尋結果的相關排名。例如,有一種排名模型可計算建議的排名分數,有幾種排名模型可對於有相關產品目錄的跨網站發佈網站計算相關排名。Special purpose ranking models compute the relevance rank for search results related to various specific ranking scenarios. For example, there is a ranking model to calculate the ranking score for recommendations and there are ranking models to calculate relevance ranks for cross-site publishing sites that have an associated product catalog.

下表列出 SharePoint Server 可用的排名模型。The following table lists the available ranking models in SharePoint Server.

特殊用途Special purpose 網站建議排名模型。Site suggestion ranking model 關係建議的排名模型。其他使用者點擊的項目將獲得較高的排名。Ranking model for social suggestions. Items that other users have clicked will get a higher ranking.

搜尋結果如何取得排名?How does a search result get a rank?

排名模型會計算搜尋結果的相關排名。搜尋結果透過稱為 排名評估 的程序取得排名。排名評估會產生排名分數。最高分數的項目將在搜尋結果中佔居最高的位置。搜尋結果依據排名分數遞減排序。A ranking model computes the relevance rank of a search result. A search result gets a rank through a process called rank evaluation. The rank evaluation results in a ranking score. Items with the highest score get the highest position in search results. Search results are sorted in descending order based on their ranking score.

例如,預設搜尋模型使用兩階段的排名評估。在第一個階段內,排名模型運用低成本的排名功能取得結果的大致排名。在第二個階段內,排名模型將其他較高成本的排名功能套用於最高排名的項目。搜尋結果頁面預設顯示這兩個排名評估階段後排名分數最高的 10 個文件。For example, the default search model uses two stages for rank evaluation. During stage one, the ranking model applies fairly inexpensive ranking features to get a gross ranking of the results. During stage two, the ranking model applies additional and more expensive rank features to the items with the highest rank. By default, the search results page shows the ten documents that have the highest ranking score after these two stages of rank evaluation.

各個排名模型都有幾個排名功能。整體排名計算之中這些排名功能的相對權數會因為排名模型而有所不同。排名功能可以取決於查詢,也可以不取決於查詢。若要計算搜尋結果的最終排名分數,將合併排名模型中所有排名功能的所有計算。Each ranking model has several ranking features. The relative weight of these ranking features in the overall ranking calculation varies per ranking model. Ranking features can be query dependent or query independent. To calculate the final ranking score of a search result, all the calculations of all the ranking features in the ranking model are combined.

排名模型使用搜尋索引的資訊,如下表所述。Ranking models use information from the search index, as explained in the following table.

搜尋索引項目的資訊Information about a search index item 描述Description
內容Content 這些是項目中包含的文字。對於文件之類的文字項目,這一般多半是文字。對於視訊之類其他類型的項目,則很少或甚至沒有內容。These are the words contained in the items. For items that are text based, such as documents, this is typically most of the text. For other types of items, such as videos, there is little or no content.
中繼資料Metadata 與標題、作者、URL 和建立日期之類項目相關聯的中繼資料。中繼資料自動從大多數類型的項目擷取而得。The metadata associated with items such as title, author, URL and creation date. Metadata is automatically extracted from most types of items.
網頁圖形資料Web graph data 這是授權單位 (來自代表性頁面設定) 及錨定文字 (來自項目相關的超連結和連結該項目的項目) 之類的資訊。This is information such as authority (from authoritative pages settings) and anchor text (from the hyperlinks associated with the item, and items linking to the item).
檔案類型File type 某些檔案類型會被視為比其他類型的排名更重要。例如,Word 和 PowerPoint 結果一般比 Excel 結果更重要。Some file types can be considered more important for ranking than others. For example, Word and PowerPoint results are typically more important than Excel results.
互動Interaction 點擊搜尋結果的次數和哪些查詢導致點擊結果的資訊。Information about the number of times a search result is clicked, and which queries led to a result being clicked.

我能夠如何影響搜尋結果的排名?How can I influence the rank of a search result?

您可以使用下列方式影響搜尋結果的排名:You can influence the ranking of search results in the following ways:

  • 查詢規則:定義查詢符合某個條件時採取的動作。Query rules: define which actions to take when a query matches a condition.

    • 將特定結果升級到搜尋結果頂端。Promote particular results to the top of the search results.

    • 新增結果區塊以便將特定結果升級。Add a result block to promote particular results.

    • 變更查詢以便變更排名。Change the rank by changing the query.

      • 依據 Managed 屬性變更排名結果的排序。Change the sorting of the ranked results based on managed properties.

      • 動態升級或降級特定結果。Dynamically promote or demote particular results.

      • 某人執行特定查詢時變更排名模型。Change the ranking model when someone runs a certain query.

    如需詳細資訊,請參閱<以查詢規則影響搜尋結果的排名>小節。See the section Influence the ranking of search results with query rules for more information.

  • 搜尋結構描述:設定 Managed 屬性的上下文。Search schema: configure the context of a managed property.

  • 建立並使用自訂排名模型。Create and use a custom ranking model.

在大多數情況下,使用 SharePoint Server 中可用的排名模型與查詢規則便足以影響排名。In most cases, using the available ranking models in SharePoint Server in combination with query rules should provide sufficient ways to influence ranking.

以查詢規則影響搜尋結果的排名Influence the ranking of search results with query rules

如果對於特定查詢的搜尋結果排名不滿意,建議嘗試使用查詢規則影響這些查詢的排名。在大多數情況下,設定查詢規則有助於達成您的目標,而且您不需要考慮變更 Managed 屬性的上下文或建立自訂排名模型。If you are not satisfied with the search result ranking for specific queries, we recommend that you try to influence the ranking for those queries with query rules. In most cases, configuring query rules will help you reach your goals, and you won't have to consider changing the context of a managed property or creating a custom ranking model.

對於各個查詢規則,您可以影響搜尋結果的排序、排名和顯示方式。各個查詢規則均包含查詢規則條件和查詢規則動作。只要查詢符合查詢規則條件,您在查詢規則中指定的查詢規則動作便會觸發。For each query rule, you can influence the way you sort, rank and display search results. Each query rule consists of a query rule condition and a query rule action. Whenever a query matches a query rule condition, the query rule action that you specify in the query rule triggers.

您可以指定查詢規則的下列查詢規則動作:You can specify the following query rule actions for a query rule:

  • 在排名的搜尋結果頂端新增升級的結果。Add promoted results on top of the ranked search results.

    您新增升級的結果 (舊版 SharePoint Server 稱為「首選」) 時,將在排名的結果之上顯示這項結果。例如,對於查詢「病假」,您可以在所有排名的結果之上新增人力資源網站的連結。When you add a promoted result, which was called Best Bets in earlier versions of SharePoint Server, you show this result above the ranked results. For example, for the query "sick leave", you can add a link to a Human Resources site above all ranked results.

  • 新增結果區塊。Add a result block.

    結果區塊將搜尋結果顯示為群組。您可以設定查詢規則,定義要在結果區塊中顯示結果的查詢。與您升級特定結果的方法相同,您也可以在符合特定查詢條件時,升級結果區塊。A result block displays search results as a group. You can configure the query rule to define for which queries you want to show the results in a result block. In the same manner as you can promote a specific result, you can promote a result block when a specified query condition applies.

  • 變更查詢以便變更排名。Change the rank by changing the query.

    • 依據 Managed 屬性排序。Sort by managed property.

      您可以指定排序搜尋結果所依據的 Managed 屬性,變更搜尋結果的排序順序,並指定應該遞增或遞減排序。您可以新增多個排序等級。如果以一或多個 Managed 屬性排序,則不需要使用排名模型將搜尋結果排名。You can change the sorting order of the search results by specifying by which managed property the search results should be sorted, and if this should be done in ascending or descending order. You can add more than one sort level. If you sort by one or more managed properties, you do not use a ranking model to rank the search results.

    • 動態排序:升級或降級搜尋結果。Dynamic ordering: promote or demote search results.

      您可以動態變更搜尋結果的排名。您可以指定特定條件適用時,何時要對於查詢變更搜尋結果的排名和數量。下表顯示您可設定的條件。You can dynamically change the ranking of search results. You can specify when you want to change the ranking of the search results for a query, and by how much, when a certain condition applies. The following table shows the conditions that you can set.

    • 變更排名模式。Change the ranking model.

      您可以變更查詢規則觸發時使用的排名模型。You can change which ranking model is used when a query rule fires.

變更排名的時機:Change ranking when: 描述Description

使用搜尋結構描述影響搜尋結果的排名Influence the ranking of search results by using the search schema

您可以變更全文檢索索引的可搜尋 Managed 屬性上下文,影響搜尋結果的排名。不過,大多數 Managed 屬性預設都已經對應到適當的上下文和全文檢索索引。不建議變更任何現有可搜尋 Managed 屬性的上下文。不過,如果您建立新的 Managed 屬性,而且想要排名模型考量這個屬性,則您必須將它對應到全文檢索索引上下文。You can influence the ranking of search results by changing the context of a searchable managed property in a full-text index. However, most managed properties are already mapped to a suitable context and full-text index by default. We do not recommend changing the context of any of the existing searchable managed properties. However, if you create a new managed property and you want this property to be considered by the ranking models, you have to map it to a full-text index context.

SharePoint Server 有多個全文檢索索引。各個全文檢索索引都有儲存於該全文檢索索引的多個 Managed 屬性。本節僅探討預設全文檢索索引,以及結合預設搜尋排名模型的一些預設全文檢索索引上下文。SharePoint Server has several full-text indexes. Each full-text index has several managed properties that are stored in that full-text index. In this section, we only discuss the default full-text index and only a few of the default full-text index contexts in combination with the default search ranking model.

全文檢索索引包含儲存於該全文檢索索引中的可搜尋 Managed 屬性所有文字。各個全文檢索索引均分成多個權數群組,也稱為上下文。不同的上下文與 Managed 屬性的相對重要性相關,這是用來計算整體相關程度排名的其中一種排名功能。上下文的數量或識別碼不重要;排名模型將指派特定上下文的比重權數來決定它的相對重要性。比重權數愈高,排名分數愈高。A full-text index contains all the text from the searchable managed properties that are stored in that full-text index. Each full-text index is divided into weight groups, also referred to as contexts. The different contexts relate to the relative importance of a managed property, which is one of the ranking features that are used to calculate the total relevance rank. The number, or ID, of a context is not important; the ranking model determines its relative importance by assigning a contribution weight to a particular context. A higher contribution weight results in a higher ranking score.

新的 Managed 屬性預設對應到上下文 0,這表示搜尋結果將傳回這些內容,但是任何排名模型均不予以考量。如果要預設搜尋排名模型考量新的 Managed 屬性,則應該將這些屬性對應到預設全文檢索索引,並對應到下表顯示的其中一處上下文。預設全文檢索索引有較多上下文,但是您只能使用下表提及的上下文。各個排名模型考量上下文的方式各不相同;該表格僅顯示預設搜尋模型如何考量預設全文檢索索引中的上下文。By default, new managed properties are mapped to context 0, which means that they are returned in the search results but are not considered by any of the ranking models. If you want a new managed property to be considered by the default search ranking model, you should map it to the default full-text index and to one of the contexts shown in the table below. There are more contexts in the default full-text index, but you should only use the contexts mentioned in the following table. Each ranking model considers the contexts differently; the table only shows how the Default Search Model considers contexts in the default full-text index.

上下文Context 此處上下文之中的 Managed 屬性範例Example of a managed property in this context 排名的相對比重權數 (預設搜尋模型及預設全文檢索索引)Relative contribution weight to ranking (Default Search Model and default full-text index)
0{0} - 僅用於重新叫用,不用於排名。Used only for recall, not for ranking.
1(1) 標題Title 0.36100.3610
22. FilenameFilename 0.15120.1512
55. AuthorAuthor 0.15810.1581
77. BodyBody 0.01940.0194

例如,您建立類型 string 的一個新的 Managed 屬性,其中包含大約 10 個字以內。您認為這個新的 Managed 屬性本身的重要性相當於現有的 Managed 屬性 Title 。在這種情況下,您應該將新的 Managed 屬性對應到上下文 1。For example, you create a new managed property of the type string that contains about ten words or less. You consider this new managed property to be about as important as the existing managed property Title. In that case, you should map the new managed property to context 1.

再舉一例。您建立類型 string 的一個 Managed 屬性,其中包含許多文字,例如某個項目的描述。您應該將這個新的 Managed 屬性對應到上下文 7,因為它的長度和重要性均類似於 Managed 屬性 BodyAnother example. You create a managed property of the type string that contains lots of words, for example a description of something. You should map this new managed property to context 7 because it is similar to the managed property Body, both in length as well as in importance.

重要

將類似重要性和大小 (字數) 的 Managed 屬性對應到相同的上下文。Map managed properties with similar importance and size (in words) to the same context.

變更 Managed 屬性的上下文之後,必須監視搜尋結果,因為變更可能不會達到預期或所需的結果。需要經過一段時間,變更才會出現在搜尋結果中,因為內容必須經過重新編製索引,才會反映搜尋結構描述的變更。如果您已經將一或多個內容來源編目,而其中包含的內容有您已經變更上下文的 Managed 屬性,則您必須重新將這些內容來源完整編目,才會在排名中看見任何變更。After changing the context of a managed property, it is important to monitor the search results, as the change may not have the expected or desired consequences. It will take some time before the changes appear in the search results, because the content has to be re-indexed before changes to the search schema are picked up. If you have already crawled one or more content sources that include content that contains the managed property that you changed the context of, you have to do a full re-crawl of those content sources before you can see any changes in the ranking.

您可以使用 Search Service 應用程式的搜尋結構描述功能,在 Advanced Searchable Settings 中變更可搜尋的 Managed 屬性上下文。如需詳細資訊,請參閱< SharePoint Server 的搜尋結構描述概觀>和<在 SharePoint Server 中管理搜尋結構描述>。You can change the context of a searchable managed property in the Advanced Searchable Settings, using the search schema feature in the Search service application. See Overview of the search schema in SharePoint Server and Manage the search schema in SharePoint Server for more information.

使用自訂排名模型影響搜尋結果的排名Influence the ranking of search results by using a custom ranking model

變更搜尋結果排名的最進階方法是建立自訂排名模型。在大多數情況下,SharePoint Server 提供的排名模型可呈現良好的排名,而且您可以使用查詢規則影響這個排名,如<以查詢規則影響搜尋結果的排名>所述The most advanced way to change the ranking of search results is to create a custom ranking model. In most cases, the ranking models that SharePoint Server supplies provide good ranking, and you can influence this ranking with query rules as discussed in Influence the ranking of search results with query rules

您可能會想要建立並使用自訂排名模型的範例:Examples of when you may want to create and use a custom ranking model:

  • 您已經建立查詢效能極為重要的搜尋體驗,而您想要使排名模型計算加快。You have created a search experience in which query performance is extremely important and you want to make the ranking model calculations faster.

  • 您已經建立自訂應用程式,並且想要建立該應用程式特定的排名模型。You have built a custom app and want to create a ranking model that is specific to that app.

  • 您已經對於特別的搜尋體驗新增特殊的 Managed 屬性,並且想要在排名計算中加入這個 Managed 屬性。You have added a special managed property for a special search experience and want to include this managed property in the ranking calculations.

警告

如果您建立自訂排名模型,這將影響使用該排名模型的所有查詢。您應該測試自訂排名模型對於多個查詢所產生的效果。If you create a custom ranking model, this influences all the queries using that ranking model. You should test the effect of the custom ranking model on many queries.

您可以閱讀 MSDN 文章<自訂排名模型以提升 SharePoint 2013 中的相關性>,了解如何建立、部署和使用自訂排名模型。You can read more about how to create, deploy and use a custom ranking model in the article Customizing ranking models to improve relevance in SharePoint 2013 on MSDN.

注意

如果您想要建立預設搜尋結果的自訂排名模型,請使用「 搜尋具有兩個線性階段的排名模型 」複本作為自訂排名模型的基本模型,這樣重新微調及自訂排名模型較為容易。If you want to create a custom ranking model for the default search results, use a copy of the Search Ranking Model with Two Linear Stages as the base model for your custom ranking model, it will be easier to re-tune and customize your ranking model.
