The issue is that you are using an analyzer on the search query and not at index time. The StandardAnalyzer that you are using at search time is lowercasing the query before searching against the index. You have a few options that I can think of:
1 - use a different analyzer at search time (one that doesn't effect case - if there is one or create one yourself) 2 - analyze the field at index time (optionally storing the original field in a non-analyzed state - if you want the original Domain) The KeywordAnalyzer probably isn't what you want because if you use it at search time you won't be able to use wildcard searching (unless you don't care about wildcard searching). -Jeff -----Original Message----- From: Michel Nadeau [mailto:aka...@gmail.com] Sent: Mon 12/14/2009 4:36 PM To: java-user@lucene.apache.org Subject: Lower/Uppercase problem when searching in a not-analyzed field Hi ! My Lucene 3.0.0 index contains a field "DOMAIN" that contains an Internet domain name - like * www.DomainName.com * www.domainname.com * www.DomainName.com/path/to/document/doc.html?a=2 This field is indexed like this - doc.add(new Field("DOMAIN", sValue, Field.Store.YES, Field.Index.NOT_ANALYZED)); When I search in this field, my search query looks like this: DOMAIN:www.DomainName* My problem is that it seems it never returns domains with uppercase letters. For example, I display all documents (using ConstantScoreQuery), and see this domain name: www.BidClerk.com ...So I know it's there - and so I search for: DOMAIN:www.BidC* - well it will *never* be found ! But whatever all-lowecase domain will be found, all the time. My guess is that the problem is the analyzer I'm using - a StandadAnalyzer: QueryParser parser = new QueryParser(Version.LUCENE_CURRENT, "content", new StandardAnalyzer(Version.LUCENE_CURRENT)); q = parser.parse(QUERY); So here are my questions: * Should I use a KeywordAnalyzer instead? * If I have domains like WWW.ASK.COM, www.ask.com, www.Ask.com, WwW.AsK.CoM- and I search for "DOMAIN: www.ask.com" ; will they all be found whatever the case?
