Applies to: ✅ Azure Data Explorer ✅ Azure Monitor ✅ Microsoft Sentinel
Filters a record set for data with a case-insensitive ending string.
The following table compares the endswith operators using the abbreviations provided:
- RHS = right-hand side of the expression
- LHS = left-hand side of the expression
| Operator | Description | Case-Sensitive | Example (yields true) |
|---|---|---|---|
endswith |
RHS is a closing subsequence of LHS | No | "Fabrikam" endswith "Kam" |
!endswith |
RHS isn't a closing subsequence of LHS | No | "Fabrikam" !endswith "brik" |
endswith_cs |
RHS is a closing subsequence of LHS | Yes | "Fabrikam" endswith_cs "kam" |
!endswith_cs |
RHS isn't a closing subsequence of LHS | Yes | "Fabrikam" !endswith_cs "brik" |

Performance tips
Note
Performance depends on the type of search and the structure of the data. For best practices, see Query best practices.
For faster results, use the case-sensitive version of an operator. For example, use endswith_cs instead of endswith.
