Re: [Exist-open] Lucene search issue with existed 2.1

[Juri L. <ju...@ex...>]

More recent versions of exist, I believe since 5.3.0, allow you to have
separate analyzers for indexing and querying.
Index without stop-words but query with them is a good combination. That
way non-phrase searches would not regard stop-words; as one usually wants,
but phrase searches can still find them as they are part of the index do
include them.
It is at least worth a try.
