Re: Question on sorting
Hi, It is because field is string and numbers are getting sorted lexicographically.It has nothing to do with number of digits.

Question on sorting
Hello, I have schema and field definition as shown below: TRACK_ID field contains "NUMERIC VALUE". When I use sort on track_id (TRACK_ID desc) it is not working properly. ->I have below values in Track_ID Doc1: "84806" Doc2: "124561" Ideally, when I use sort command, query result should be Doc2: "124561" Doc1: "84806" But I'm getting: Doc1: "84806" Doc2: "124561" Is this because, field type is string and doc1 has 5 digits and doc2 has 6 digits? Please provide solution for this. Thanks, Srinivas DISCLAIMER: E-mails and attachments from Bamboo Rose, LLC are confidential.

RE: Question about sorting by a field
Yes, that works! I had to boost the firstDestination field to have it well sorted. Any ideas why the score might be equally for all the documents returned? Thanks a lot!

Question about sorting by a field
Hi all, I've been working with solr for a few months now and so far I only had a few issues trying to implement some functionality, but this has gone above my current solr skills, so any help or guidance is greatly appreciated. I have a multivalued field consited which contains destinations like: Paris, Rome, London doc id=1 destinations value=quot;Buenos Airesquot;/ value=quot;Parisquot;/ value=quot;Londonquot;/ value=quot;Romequot;/ /destinations /doc doc id=2 destinations value=quot;Londonquot;/ value=quot;Buenos Airesquot;/ value=quot;Parisquot;/ value=quot;Romequot;/ /destinations /doc Ok so those are my documents. Then I query searching documents containing Buenos Aires as a destination, those two documents will come as results, so far so good. Now, what is really important for me, is that the first results are the ones that match the first destination, since the user will want to see those first as well. My question is, how can I sort this results ? What should I use? Is there a way to do this with Solr? I've been reading on how to pull this out by using boosts but that doesn't seem to be working on my end so far. Thanks in advanced!

RE: Question about sorting by a field
How about having a single-valued field named firstDestination that has the first destination in the list, and then your query could be something like 'destination:Buenos Aires firstDestination:Buenos Aires'. Docs that match both should have a higher score and thus will be listed first. -Michael
Question about sorting by coordination factor
Hi, I am trying to solve a sorting problem using Solr. The sorting requirements are a bit complicated. I have to sort the documents by three different criteria: - First by number of keywords that match (coordination factor) - Then, within the documents that match the same number of keywords, sort first the documents that match a user value (country) and then the rest. - Then within those two blocks, sort by a document value (popularity). I have managed to make the second and third criteria to work, with a query like this: http://localhost:8983/solr/select/?q=description%3Afootballversion=2.2start=0rows=10indent=onqq=country_uk:truesort=map%28query%28$qq,-1%29,0,999,1%29%20desc,popularity%20desc This gets with the query function a positive value for the documents that match the country, and a negative for the ones that don't, and then maps those ones to 1, so I have two blocks of documents with sorting value of 1 and -1, which works for me cause ties are then sorted by popularity. But as you see, this is only searching for 1 keyword. My problem comes with the first requirement when we search for more than one keyword, because as I understand, I would like to sort by the coordination factor, which is the number of query keywords that each document matches. The problem is that there's no Function Query I can use to get that value, so I don't know how to proceed. I was trying to understand if there was a way to split the regular score into sets which should mean that the same number of keywords was matched, but the score depends on different things, and the range of values can be arbitrary, so I'm not able to make such a function. Is there any solution to this? Thanks, Jesus.
Re: Question about sorting by coordination factor
Say you're trying to match terms A, B, C. Would something like (A AND B AND C)^1000 OR (A AND B)^100 OR (A AND C)^100 OR (B AND C)^100 OR A OR B OR C work? It wouldn't be an absolute ordering, but it would tend to push the documents where all three terms matched toward the top. It would get really cumbersome if there were lots of terms, but.

The problem with this is that that would give better score to the documents with most number of matches, but then I have to sort internally those groups. So I'd need a sort=score,xxx,yyy and the score would not be equal for the documents which match the same number of keywords. I would need to have as many groups as keywords, and within each group all documents need to have the same value for that sorting criteria (score or a function or whatever), so that they tie, and they move to the next sorting criteria. Thanks, Jesus.
Re: Question about sorting by coordination factor
Ahhh, you're right. I know there's been some discussion in the past about how to find out the number of terms that matched, but don't remember the outcome off-hand. You might try searching the mail archive for something like number of matching terms or some such.

Question on sorting
Hi, I have a Solr index with an awful lot of tiny documents in it (hundreds of millions) each having a few fields. I can query the index without problem and retrieve results sorted on score. I am now exploring the possibility of sorting on other fields. The typical number of results from queries is in the 100s or 1000s, so tiny in regard to index size. From what I remember of Lucene, it had (still has?) to build a FieldCache prior to sorting, and this FieldCache contains all field values for the field to sort on right? My question is, is there a way around that behaviour of the field cache, i.e. could a filter query somehow limit the values loaded in the FieldCache? Is there otherwise a WTH (Well Known Hack) to be able to sort on fields when an index has lots (100s of 1000s) of values for that field? Any help appreciated, Mathias.

question about sorting
Hi, My sorting fields include both TextField type and StrField type. Because TextField uses TokenizerFactory, they can't be sorted. I have to copy each TextField to a StrField and sort on those StrFields. Does anyone know if there is a better way to do that? Thanks Xuesong

question regarding sorting
I am having strange behaviour experimenting with the example solr server. Via the tutorial - except I set up my own schema. Anyway, here's the issue - if I provide the explicit sort param in my request, the sort does not seem to execute, however if I have the encoded sort via using ; field desc for example, sorting does work. Is this expected behaviour? Is there something I'm missing. Eg; This does not sort: http://localhost:8983/solr/select/?indent=onq=24sort=lastmodified% 20descfl=uniquekey,lastmodified This does: http://localhost:8983/solr/select/?indent=onq=24;%20lastmodified% 20ascfl=uniquekey,lastmodified Anyone know why? James
Re: question regarding sorting
Hi James I think this feature is in 1.2, which is not released yet (in CVS/nightly) From http://wiki.apache.org/solr/StandardRequestHandler Note, in solr1.1 the query and sort parameter were combined as a single parameter separated with a ';' (q=name:solr; date desc). Since solr1.2, it is recommend to use the sort parameter described in CommonQueryParameters. -Nick On 5/24/07, James O'Rourke [EMAIL PROTECTED] wrote: I am having strange behaviour experimenting with the example solr server.
