C# Class Lucene.Net.Search.RegexpQuery

A fast regular expression query based on the Lucene.Net.Util.Automaton package.

Comparisons are fast
The term dictionary is enumerated in an intelligent way, to avoid comparisons. See AutomatonQuery for more details.

The supported syntax is documented in the 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 .*
