(In reply to Philip Hazel from comment #13)

Thanks for another constructive feedback.

* How are the chances to change the mentioned software inefficiency in
significant ways?

* Can your current regular expression engine perform cost analysis so that it
could determine at which number of “key words” (or “branches”) in the
alternation it would make sense to work also with a corresponding trie variant
which would be generated on demand as a special service?

* Will advanced indexing approaches become feasible here?
