Hello, I'm a bit new to search indexing and I'm hoping some of you here can help me with an e-mail application I'm working on. I have a mail retrieval program that accesses multiple POP accounts in parallel, and parses each message into a database. I would like to add a new document to a solr index each time I process a message.
My first intuition is to give each user their own index. My thinking here is that querying would be faster (since each user's index would be much smaller than one big index,) and, more importantly, that I would dodge any concurrency issues stemming from multiple threads trying to update the same index simultaneously. I realize that Lucene implements a locking mechanism to protect against concurrent access, but I seem to hit the lock access timeout quite easily with only a couple threads. After looking at solr, I would really like to take advantage of the many features it adds to Lucene, but it doesn't look like I'll be able to achieve multiple indexes. Am I completely off in thinking that I need multiple indexes? Is there some best practice for this sort of thing that I haven't stumbled upon? Any advice would be greatly appreciated.
