Detailed Description
Implements the wildcard search query.
Supported wildcards are *, which matches any character sequence (including the empty one), and ?, which matches any single character. Note this query can be slow, as it needs to iterate over all terms. In order to prevent extremely slow WildcardQueries, a Wildcard term must not start with one of the wildcards * or ?.
