Filters a record set for data with a case-sensitive ending string.
has searches for indexed terms, where a term is three or more characters. If your term is fewer than three
characters, the query scans the values in the column, which is slower than looking up the term in the term index.
The following table provides a comparison of the
||RHS is a term suffix in LHS||No||
||RHS isn't a term suffix in LHS||No||
||RHS is a term suffix in LHS||Yes||
||RHS isn't a term suffix in LHS||Yes||
- RHS = right hand side of the expression
- LHS = left hand side of the expression
For further information about other operators and to determine which operator is most appropriate for your query, see datatype string operators.
Performance depends on the type of search and the structure of the data.
For faster results, use the case-sensitive version of an operator, for example,
- T - The tabular input whose records are to be filtered.
- col - The column to filter.
- expression - Scalar or literal expression.
Rows in T for which the predicate is
In this example the query looks for log sources that end with the value In a case sensitive manner.
