RE: search a subdirectory (New to Lucene)
I reindexed with the path as a keyword field and now the PrefixQuery filter does exactly what I need. Thanks! I'm going to hold off on the paragraph-level indexing for now, but that does sound interesting. many thanks, John -Original Message- From: Erik Hatcher [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 22, 2006 3:18 PM To: java-user@lucene.apache.org Subject: Re: search a subdirectory (New to Lucene) I presume by saying subdirectory you're referring to filesystem directories and you're indexing a directory tree of files.
