To have a powerful search system à la Spotlight or Beagle we need to
think :
- metadatas database
- content index database
LuceneKit provides the later.
Just a comment.
Lucene is a general index and search engine.
Applications are responsible for deciding
which information should go into the index.
Therefore, if an application put the metadata into
the index, lucene can search on it.
In the other word, lucene can search on meta-data
and content. There is not difference to lucene.
It all depends on how applications feed information to lucene.
Thanks I was forgetting this point.
However to have best performance possible it is better to avoid search
in content index when you just need to look at metadatas (with
Spotlight Apple has chosen to rely on two separate databases for
metadata and content index).
Well may be Lucene allows such keyed search but I don't remember about
such possibility. Do you know about such possibility ?
hmm Beagle seems to put everything in a single database (both metadatas
and content index).
I need to reread Lucene documentation :-)
