Solandra doesn't use secondary indexes, the functionality is too limited for the lucene api.  It maintain's it's own indexes in regular column families.  I suggest you look at Solr and decide if this is the functionality you need, Solandra offers the same api but on Cassandra's distributed model.

You need to maintain a huge number of distinct indexes.

Are we talking about secondary indexes? If yes, this sounds like exactly my problem. There is so little documentation! - but I think that if I read all there is on GitHub, I can probably start using it.

Thank you,

I need to store, say, 10M-100M documents, with each document having say 100 fields, like author, creation date, access date, etc., and then I want to ask questions like

give me all documents whose author is like abc**, and creation date any time in 2010 and access date in 2010-2011, and so on, perhaps 10-20 conditions, matching a list of some keywords.

What's best, Lucene, Katta, Cassandra CF with secondary indices, or plan scan and compare of every record?

Thanks a bunch!
