Subject Re: Full text search - is it coming? If yes, approx when.

Couchdb + Lucene (Elasticsearch etc.) is a really great combination
and definitely enough on the server side... IMHO what is missing is a
full text engine for Couchdb on mobile - that would be a killer...
Currently the only full text search library on mobile devices is
sqlite fts3 which is great but doesn't have replication. Maybe someone
could implement something based on sqlite fts3 which uses the changes
stream to keep in sync...?

How do you search couchdb on mobile devices?

wrt. the original post? Cloudant's search is built on Lucene.
