You write that you index the string under the "url" field. Do you also index it under "title"? If not, that can explain why title:"Rahul Dravid" does not work for you.
Also, did you try to look at the index w/ Luke? It will show you what are the terms in the index. Another thing which is always good to debug such things is to create a StandardAnalyzer, then request a tokenStream() from it, passing a StringReader w/ the text you want to parse. Then just print the tokens returned. I've done that, using the version from trunk, w/ Version.2_4, and the tokens that are extracted are: (http,0,4,type=<ALPHANUM>) (en.wikipedia.org,7,23,type=<HOST>) (wiki,24,28,type=<ALPHANUM>) (rahul,29,34,type=<ALPHANUM>) (dravid,35,41,type=<ALPHANUM>) So: 1) You don't get results for title:"Rahul Dravid" since you index it under "url" and not "title". 2) url:"wiki/Rahul_Dravid" works, since it looks for a phrase that exists in the index (look at the last 3 tokens produced by the Analyzer, in the output above). 3) ur:"<entire string" also works, since you index all of it under the "url" field. Does this explain the behavior you see? Shai On Sun, Aug 2, 2009 at 1:27 PM, prashant ullegaddi <prashullega...@gmail.com > wrote: > Hi, > > I've indexed some 50million documents.
