Examples of WildcardQuery

org.apache.jackrabbit.core.query.lucene.WildcardQuery
Implements a wildcard query on a lucene field with an embedded property name and a pattern.
Wildcards are:
- % : matches zero or more characters
- _ : matches exactly one character
org.apache.lucene.search.WildcardQuery
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 many terms. In order to prevent extremely slow WildcardQueries, a Wildcard term should not start with one of the wildcards * or ?.
This query uses the {@link MultiTermQuery#CONSTANT_SCORE_AUTO_REWRITE_DEFAULT}rewrite method. @see WildcardTermEnum
