How can I find `includeFlags` which was earlier in Elasticsearch `TermBuilders`?

This is only present in `SignificantTermBuilders`!!

Hi,

thanks for spotting this. I have created the following tickets on Github:

- Add regex flags to TermsBuilder: [https://github.com/elastic/elasticsearch/issues/16228](https://github.com/elastic/elasticsearch/issues/16228)
- Align the regex implementation in SignificantTermsBuilder and TermsBuilder: [https://github.com/elastic/elasticsearch/issues/16231](https://github.com/elastic/elasticsearch/issues/16231)

However, note that the internal implementation has changed from `java.util.Regex` to `org.apache.lucene.util.automaton.RegExp` so the newly exposed flags will have different semantics (see the [Lucene docs on Regexp](http://lucene.apache.org/core/4_9_0/core/org/apache/lucene/util/automaton/RegExp.html)) once the tickets are implemented.

Daniel
