You can add multiple values for a field to a single document. Document doc = new Document(); String[] paths = whatever.split(","); for (String p : paths) { doc.add(new Field("path", p, whatever ...); }
For searching, assuming you only want to be able to wildcard on path delimiters, you could index /Top/My Prods/Book Prods/Text Books /Top/My Prods/Book Prods /Top/My Prods /Top which would let you search on any of them. You'll want to pick or build an analyzer that behaves as you want wrt case matching and not splitting on the /. Sometime it can be easier to replace a character e.g. / to _. I think there is a lucene class that can do that, maybe MappingCharFilter, if you don't want to do it yourself. You will of course need to be consistent and do the same processing at index and search time. -- Ian.
