# Wildcards in Queries

Use Wildcard matching sparingly, because it slows the Content component performance.

You can use the following Wildcard characters in query `Text` and `FieldText` queries:

? | to match one character.
* | to match zero, one, or more characters.

You can use the `UnstemmedMinDocOccs` parameter in the `[Server]` section of the configuration file to specify the number of documents in which a term must occur to consider it in a Wildcard search.

NOTE: To use Wildcards to search for numbers, set `SplitNumbers` in the `[Server]` section to `False`. For more information, refer to the Content component Reference.
