Multiple or single index in Lucene?
I have to index different kinds of data (text documents, forum messages, user profile data, etc) that should be searched together (ie, a single search would return results of the different kinds of data).

 - What are the advantages and disadvantages of having multiple indexes, one for each type of data?

 - And the advantages and disadvantages of having a single index for all kinds of data?

Thank you.
