Azure 认知搜索中的预览功能Preview features in Azure Cognitive Search

本文列出了当前预览版中的功能。This article lists features currently in preview. 从此列表中删除了从预览版转换为公开发行版本的功能。Features that transition from preview to general availability are removed from this list. 可以查看服务更新或有关公开上市的公告的新增功能You can check Service Updates or What's New for announcements regarding general availability.

虽然门户和 .NET SDK 中可能提供某些预览功能,但 REST API 始终具有预览功能。While some preview features might be available in the portal and .NET SDK, the REST API always has preview features.

重要

提供的预览版功能不附带服务级别协议,我们不建议将其用于生产工作负荷。Preview functionality is provided without a service level agreement, and is not recommended for production workloads. 有关详细信息,请参阅 Microsoft Azure 预览版补充使用条款For more information, see Supplemental Terms of Use for Microsoft Azure Previews.

AI 扩充功能AI enrichment features

通过预览版搜索 API探索 AI 扩充的最新增强功能。Explore the latest enhancements to AI enrichment through the preview Search API.

自定义实体查找技术(预览版)Custom Entity Lookup skill (preview) 一项认知技能,可查找自定义的、用户定义的单词和短语列表中的文本。A cognitive skill that looks for text from a custom, user-defined list of words and phrases. 使用此列表,它将标记具有任何匹配实体的所有文档。Using this list, it labels all documents with any matching entities. 该技能还支持一定程度的模糊匹配,可用于查找类似但不完全完全相同的匹配项。The skill also supports a degree of fuzzy matching that can be applied to find matches that are similar but not quite exact.
PII 检测技能(预览)PII Detection skill (preview) 在编制索引期间使用的一项认知技能,可从输入文本中提取个人身份信息,并提供以各种方式从文本中屏蔽该文本的选项。A cognitive skill used during indexing that extracts personally identifiable information from an input text and gives you the option to mask it from that text in various ways.
增量扩充(预览版)Incremental enrichment (preview) 将缓存添加到扩充管道,以便在目标修改(如对技能组合或其他对象的更新)不更改内容时重复使用现有输出。Adds caching to an enrichment pipeline, allowing you to reuse existing output if a targeted modification, such as an update to a skillset or another object, does not change the content. 缓存仅适用于技能组合生成的丰富文档。Caching applies only to enriched documents produced by a skillset.
知识存储(预览版)Knowledge store (preview) 基于 AI 的扩充管道的新目标。A new destination of an AI-based enrichment pipeline. 物理数据结构存在于 Azure Blob 存储和 Azure 表存储中,并在运行具有附加认知技能组合的索引器时创建并填充。The physical data structure exists in Azure Blob storage and Azure Table storage, and it is created and populated when you run an indexer that has an attached cognitive skillset. 在技能组合定义内指定知识存储本身的定义。The definition of a knowledge store itself is specified within a skillset definition. 在知识存储定义中,通过确定数据的形状、数据是否存储在表存储或 Blob 存储中,以及是否有多个视图的投影元素来控制数据的物理结构。Within the knowledge store definition, you control the physical structures of your data through projection elements that determine how data is shaped, whether data is stored in Table storage or Blob storage, and whether there are multiple views.

索引和查询功能Indexing and query features

预览搜索 API 中提供了索引器预览功能。Indexer preview features are available in preview Search API.

Cosmos DB 索引器Cosmos DB indexer 支持 MongoDB API (预览)、Gremlin API (预览)和 Cassandra API (预览版) API 类型。Support for MongoDB API (preview), Gremlin API (preview), and Cassandra API (preview) API types.
Azure Data Lake Storage Gen2 索引器(预览版)Azure Data Lake Storage Gen2 indexer (preview) 索引 Data Lake Storage Gen2 的内容和元数据。Index content and metadata from Data Lake Storage Gen2.
moreLikeThis 查询参数(预览)moreLikeThis query parameter (preview) 查找与特定文档相关的文档。Finds documents that are relevant to a specific document. 早期预览版中已有此功能。This feature has been in earlier previews.

管理功能Management features

私有终结点支持Private Endpoint support 你可以使用安全的客户端(例如虚拟机)创建虚拟网络,然后创建使用专用终结点的搜索服务。You can create a virtual network with a secure client (such as a virtual machine), and then create a search service that uses Private Endpoint.
IP 访问限制IP access restriction 使用管理 REST API api-version=2019-10-01-Preview ,你可以创建对允许访问哪些 IP 地址有限制的服务。Using api-version=2019-10-01-Preview of the Management REST API, you can create a service that has restrictions on which IP addresses are allowed access.

更早的预览功能Earlier preview features

以前的预览中公布的功能(如果尚未转换为公开上市)仍处于公开预览状态。Features announced in earlier previews, if they have not transitioned to general availability, are still in public preview. 如果你正在调用使用较早预览版 API 版本的 API,可以继续使用该版本或切换到 2019-05-06-Preview,而不会对预期行为作出任何更改。If you're calling an API with an earlier preview api-version, you can continue to use that version or switch to 2019-05-06-Preview with no changes to expected behavior.

如何调用预览版 APIHow to call a preview API

早期预览版仍然可用,但随着时间推移会变得过时。Older previews are still operational but become stale over time. 如果代码调用 api-version=2016-09-01-Previewapi-version=2017-11-11-Preview,那些调用仍然有效。If your code calls api-version=2016-09-01-Preview or api-version=2017-11-11-Preview, those calls are still valid. 但是,只有最新预览版会获得改进。However, only the newest preview version is refreshed with improvements.

以下示例语法说明了对预览 API 版本的调用。The following example syntax illustrates a call to the preview API version.

GET https://[service name].search.windows.net/indexes/[index name]/docs?search=*&api-version=2019-05-06-Preview

Azure 认知搜索服务在多个版本中可用。Azure Cognitive Search service is available in multiple versions. 有关详细信息,请参阅 API 版本For more information, see API versions.
