The wildcardMax element is a child of the parserOptions element. It has no child elements.

Oracle ATG Web Commerce Search can handle wildcard and regular expressions in the user’s query, as described in the User-Entered Operators chapter. These patterns are expanded to a set of index terms which are then used during retrieval. Search limits the number of expansions to prevent an explosion of terms that could greatly degrade performance, such as s*. The maximum expansions per pattern are specified by the following option:

<wildcardMax>max</wildcardMax>

The value defaults to 20. Setting this option to 0 disables the interpretation of wild card and regular expressions in user queries.
