Re: [hibernate-dev] [infinispan-dev] [HSearch] DSL for Lucene queries (was: Re: Query module new API and configurations)
Just wanted to get this topic re-started again.
Essentially what I think this project/DSL/module/thingy-bob is thought
to become: -
A simple package where a user can build Lucene queries without having
to know too much about Lucene itself. If I'm headed down the wrong
thought path then just thwack me.

What do you really gain compared to native Lucene queries?
What's gained I believe is the fact that people can build complex
lucene queries easier. Currently, it's a bit clunky imo so if we
provide a cleaner way to build them it can prove beneficial to any
lucene user (myself included for querying on Infinispan).
Any other thoughts?
If your API achieves exactly the same as what's possible with
Lucene
it is just a 'useless' wrapper.
A wrapper around native Lucene queries would make sense if it could
somehow use some of the Hibernate Search specific meta data. As an
extreme example one could generate some meta classes a la JPA2. This
way
one could ensure that you can get help with which field names are
available.
