[infinispan-dev] new Infinispan Query API - ISPN-194

[Sanne Grinovero]

I need to pick the final name for the Query entry point ASAP,
proposals so far:

- SearchManager (1 vote)
- SearchProvider (1 vote)
- GridSearcher (1 vote)
- TheGridReaper (no votes)

Galder pointed out that "SearchManager" is being consistent with other
Infinispan names.

More ideas?
