using lucene as a dictionary database?

[aurora <au...@gmail.com>]

Besides full text indexing, I need a database that represent a large
dictionary like:

  (key1, key2) -> docid

I am considering between building a home grown solution and using
Berkeley DB. Then I think I was using Lucene anyway, wouldn't it make
sense use it as my database too? Just make key1 and key2 two keyword
fields and an UnIndexed field for docid?

I need to do something like

  get(key1, key2) -> docid
  get(key1) -> list of docid

This need to be fast

  add( list of (key1,key2,docid) )

This would be done perhaps once a day in a batch.

My experience with Lucene is its very efficient in terms of speed and
storage size. Would this be a right usage with Lucene?

Yes, you could certainly use Lucene for that.  If public APIs don't do
it for you, there is certainly some nice code under the hood that you
can reuse or borrow.
