Non-Full-Text Predicates
The Microsoft Windows Search query language supports six non-full-text search predicates. The predicates described in this section are listed in the following table.
| Non-full-text predicate | Description |
|---|---|
| ALL BITWISE and SOME BITWISE | Is a set of keywords that are about testing the bits in an integral type. |
| DATEADD Function | Performs time and date calculations for matching properties having date types. Use the DATEADD function to obtain dates and times in a specified amount of time before the present. |
| LIKE Predicate | Compares column values using simple pattern matching with wildcard characters. |
| Literal Value Comparison | Compares column values against string, date, time stamp, numeric, and other literal values. This predicate supports inequalities such as greater than ('>'), and less than ('<'). |
| Multi-Valued (ARRAY) Comparisons | Compares multivalued columns against a multivalued array of literals. |
| NULL Predicate | Detects column values that are undefined for the document. |
Important
Search queries using the NULL predicate can require that Windows Search scan the entire catalog, which might slow down the query's performance.
