Examples of RegexpQuery

The supported syntax is documented in the {@link RegExp} class.Note this might be different than other regular expression implementations. For some alternatives with different syntax, look under the sandbox.

Note this query can be slow, as it needs to iterate over many terms. In order to prevent extremely slow RegexpQueries, a Regexp term should not start with the expression .* @see RegExp @lucene.experimental
