RE: AW: Leading wildcards
Just cant figure this out, ...or do I have to do this programmatically? Have a facet, and field in an document called estimatedRepairs, it is declared in the schema.xml as field name=estimatedRepairs type=sfloat indexed=true stored=true multiValued=true/ I execute a query with the below parameters q=state%3Avirgina; facet.query=estimatedRepairs:[*+TO+1000.0] facet.query=estimatedRepairs:[1000.0+TO+*] facet=true facet.field=state facet.field=country facet.field=zip facet.field=estimatedProfit facet.field=marketValue facet.field=numberOfBaths facet.field=numberOfBeds facet.field=price facet.field=type facet.limit=10 facet.zeros=false facet.missing=false version=2.2 debugQuery=true However my results show facet name: [estimatedRepairs] value count: [10] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [24153.0] , count: [7] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [1469.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [4249.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [16444.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [21555.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [23132.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [25669.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [26160.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [27058.0] , count: [6] [ListingApp] INFO [main] ListingManagerImplTest.testCreateQueryFromSearchParams(186) | count Name: [171.0] , count: [5] AND I DON'T WANT THIS. I want it to show Something like by estimated Repairs. 1 to 1000[23] 1000 - 2000[53] I thought facet.query allows me to do this? If not what will let SOLR generate the query counts, for the results in intervals of 1000 Jeryl Cook ^ Pharaoh ^ http://pharaohofkush.blogspot.com/ 1f u c4n r34d th1s u r34lly n33d t0 g37 l41d

PLEASE REMOVE ME FROM THIS MAILING LIST!!! Whoever manages this list, can you please remove me i have tried sending emails to the unsubscribe email, but i just keep getting more emails. This is really an issue for me... so your help would be great!

It is certianly an odd bit of behavior, and we should try to be consistent. I think it it would be fairly straight forward to make the SolrQueryParser *always* test that the field is viable according the IndexSchema ... would you mind opening a bug in Jira for this? -Hoss _ Download Messenger.

Re: AW: Leading wildcards
hey, we've stumbled on something weird while using wildcards we enabled leading wildcards in solr (see previous message from Christian Burkamp) when we do a search on a nonexisting field, we get a SolrException: undefined field (this was for query nonfield:test) but when we use wildcards in our query, we dont get the undefined field exception, so the query nonfield:*test works fine ... just zero results... is this normal behaviour ? Burkamp, Christian [EMAIL PROTECTED] 19/04/2007 12:37 Please respond to solr-user@lucene.apache.org To solr-user@lucene.apache.org cc Subject AW: Leading wildcards Hi there, Solr does not support leading wildcards, because it uses Lucene's standard QueryParser class without changing the defaults. You can easily change this by inserting the line parser.setAllowLeadingWildcards(true); in QueryParsing.java line 92. (This is after creating a QueryParser instance in QueryParsing.parseQuery(...)) and it obviously means that you have to change solr's source code. It would be nice to have an option in the schema to switch leading wildcards on or off per field. Leading wildcards really make no sense on richly populated fields because queries tend to result in too many clauses exceptions most of the time. This works for leading wildcards. Unfortunately it does not enable searches with leading AND trailing wildcards. (E.g. searching for *lega* does not find results even if the term elegance is in the index. If you put a second asterisk at the end, the term elegance is found. (search for *lega** to get hits). Can anybody explain this though it seems to be more of a lucene QueryParser issue? -- Christian -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 19.

Re: AW: Leading wildcards
thanks, this worked like a charm !! we built a custom QueryParser and we integrated the *foo** in it, so basically we can now search leading, trailing and both ... only crappy thing is the max Boolean clauses, but i'm going to look into that after the weekend for the next release of Solr : do not make this default, too many risks but do make an option in the config to enable it, it's a very nice feature thanks everybody for the help and have a nice weekend, maarten Burkamp, Christian [EMAIL PROTECTED] 19/04/2007 12:37 Please respond to solr-user@lucene.apache.org To solr-user@lucene.apache.org cc Subject AW: Leading wildcards Hi there, Solr does not support leading wildcards, because it uses Lucene's standard QueryParser class without changing the defaults.
