Looking through the user and dev mailing lists I see a couple responses to searching across multiple indices (indices or indexes??). Back in 2006 was the last lucene's MultiSearcher was considered. Apparently, then there was concern about using it. It has been improved and finalized in the lucene-core since then, no?
http://www.mail-archive.com/[email protected]/msg04486.html Also, there is a improvement ticket (NUTCH-480) that can use different indices. But it does not use MultiSearcher and looks like it searches different indices not necessary combining those indicies as MultiSearcher does. https://issues.apache.org/jira/browse/NUTCH-480 My question is, has anybody built something like this into an application? If no, it looks like I'd have to change the private init method of NutchBean to accomplish this. Could instantiating the searcher be abstracted out of that method allowing NutchBean to be extended with a different searcher or injected with different searcher(s)? And/or same thing with IndexSearcher: the lucene-core searcher is instantiated in a private init method. Thanks for your time! Chris
