[Yanel-dev] Upgrading Lucene

[Michael Wechner]

Hi Together

I have recently tried to integrate Elasticsearch into Yanel, but have
trouble doing this, because Elasticsearch requires a more recent Lucene
version than Yarep is using (2.9.2).


Lucene already offers version 6.6.0
(https://lucene.apache.org/core/downloads.html) and I think it would be
good to upgrade Lucene finally. I am not sure whether search indices are
still compatible, but one could re-generate a search index.

What do you think? Any objections?

Thanks

Michael
