Re: How to round solr score ?
Thanks for your replies. I am actually doing the frange approach for now. The only downside I see there is it makes the function call twice, calling createWeight() twice. And so my social connections are evaluated twice which is quite heavy operation. So I was thinking if I could get away with one additional call.

agreed, more details would be helpful.
FWIW: the only way available to facet on functions is to use facet.query
along with the {!frange} paser to create facet constraints based on ranges
of function values that you specify.
there is no othe way i can think of to facet over function values -- there
is an open issue where people were discussing it, but i don't think there
wa ever a functional patch...

Re: How to round solr score ?
Hi , As per this post here http://grokbase.com/t/lucene/solr-user/131jzcg3q2/how-to-round-solr-score. I was able to use my custom fn in sort(defType=func&q=socialDegree(id,1)&fl=score,*&sort=score%20asc) - works, but can't facet on the same(defType=func&q=socialDegree(id,1)&fl=score,*&facet=true&facet.field=score) - doesn't work. Exception: org.apache.solr.common.SolrException: undefined field: "score" at org.apache.solr.schema.IndexSchema.getField(IndexSchema.java:965) at org.apache.solr.request.SimpleFacets.getTermCounts(SimpleFacets.java:294) at org.apache.solr.request.SimpleFacets.getFacetFieldCounts(SimpleFacets.java:423) at org.apache.solr.request.SimpleFacets.getFacetCounts(SimpleFacets.java:205) at org.apache.solr.handler.component.FacetComponent.process(FacetComponent.java:78) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:208) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:135) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1816) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:448) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:269) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1307) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:453) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:137) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:560) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:231) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1072) Is there any way by which we can achieve this?

You have to use rint() in combination with query()
If I understand your requirements correctly, something
along the lines below should work:
http://localhost:8983/solr/select/?defType=func&q=rint(query({!v="text:term"}))&fl=score,*&sort=score
desc,price asc
should work, where one is searching for "term" in the field "text".
The score is displayed in the returned fields to demonstrate that
it has been rounded off.

Gora
Re: How to round solr score ?
Hey Gora, thanks for the fast answer! I Had tried the rint(score) function before(it would be perfect in my case) but it didnt work out, i guess it only works with indexed fields, so i got the "sort param could not be parsed as a query, and is not a field that exists in the index: rint(score)" error, And with the query() function i didnt got any successful result... Im stuck in the same cenario as squaro. if two docs have score of 1.67989 and 1.6767, I would like to sort them by price. My &sort rules ae something like: &sort=score desc, price asc -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-round-solr-score-tp495198p4034551.html Sent from the Solr - User mailing list archive at Nabble.com.

Do not have a Solr index handy at the moment to check, but it should be possible to do this with function queries. Please see the rint() and query() function at http://wiki.apache.org/solr/FunctionQuery Regards, Gora

You are indeed right. However, we can do scale(round(score, 2), 1, 10) or we can create a new scale function as you said. -- Regards, Shalin Shekhar Mangar.

Re: How to round solr score ?
I think what you want to do is add in a function query that gives values in that range. There is no need to round the scores. That doesn't do anything but throw away information. wunder On 3/30/09 10:07 AM, "Shalin Shekhar Mangar" wrote: > On Mon, Mar 30, 2009 at 10:04 PM, squaro wrote: > >> >> Hello, >> >> I would like to cut solr score to 3 or 4 digits . >> Indeed I would like to be able to sort by score, then by another critria ( >> price for example). >> So if two docs have score of 1.67989 and 1.6767, I would like to sort them >> by price. >> >> Do you have any idea how I could do that ? > > > I don't there there is an existing way to round them.

Hello, I would like to cut solr score to 3 or 4 digits . Indeed I would like to be able to sort by score, then by another critria ( price for example). So if two docs have score of 1.67989 and 1.6767, I would like to sort them by price.
