Instead of using QueryParser.Parse, what if you make a WildcardQuery directly? I had similar troubles getting prefix queries (for ajax) working properly, never did solve it.

IndexSearcher is = new IndexSearcher(directory); //Build a query based on the searchString and cached analyzer QueryParser parser = new QueryParser(ROW_NUMBER,analyzer); Query query = parser.parse(luceneSearch); System.out.println("Parsed Search Query Is"+query.toString()+"of type:"+query.getClass()); //run the search Hits hits = is.search(query); Iterator i = hits.iterator(); while(i.hasNext()) { Document doc = ((Hit)i.next()).getDocument(); matchingRows.add(new Integer(doc.getField(ROW_NUMBER).stringValue())); } } catch (Exception e) { e.printStackTrace(); } System.out.println("Search Query Results Set:"+matchingRows.size()); return matchingRows; } Mark Miller wrote: > >> >> >> Perhaps not like whitespaceanalyzer does in all cases, but this code >> >> QueryParser qp = new QueryParser("field", new >> WhitespaceAnalyzer()); >> >> Query q = qp.parse("Does this tokenize*"); >> System.out.println(q.toString()); >> >> produces >> >> field:Does field:this field:tokenize* >> >> >> >> while this code >> QueryParser qp = new QueryParser("field", new >> KeywordAnalyzer()); >> >> Query q = qp.parse("Does this tokenize*"); >> System.out.println(q.toString()); >> >> >> Produces: >> field:Does field:this field:tokenize* >> >> The only difference is using KeywordAnalyzer rather than >> WhitespaceAnalyzer. >> >> I sure don't see the difference, and it's puzzled me on and off. >> >> Erick > QueryParser breaks up "Does this tokenize*" before it even gets to the > Analyzer...each space separated term is fed to the analyzer one at a > time...unless they are surrounded in quotes in which case the whole > string in the quotes is fed into the analyzer. > > - Mark > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
