I don’t believe the native FST supports backreferences, and I don’t think it would be easy to add support either. Not sure about the lucene FST index. As mentioned above, LIKE statements (e.g. LIKE ‘%foo%’) can’t express all regular expression features, which should reduce the scope of the edge cases to be considered. This definitely needs benchmarking for at least the following scenarios; * Single like statement * N like statements combined with OR for each of: * no FST index - both raw and dictionarized * Lucene FST index * Native FST index -- This is an automated message from the Apache Git Service.
