Hello, I am using the solr version 4.4.0, when I'm using FunctionQuery with boolean fields, it seems that the default field value is "true" for documents without a value in the field.
The page http://wiki.apache.org/solr/FunctionQuery#field says "0 is returned for documents without a value in the field." so we could expect that the field value would be "false". Starting from the "SolrCloud - Getting Started" page with the document exampledocs/ipod_video.xml and removing the boolean field "inStock": <field name="inStock">true</field> demonstrates the problem. When requesting with bf=if(inStock,10,0) : curl -sS "http://localhost:8983/solr/select?q=*:*&bf=if%28inStock,10,0%29&defType=edismax&debugQuery=true"; Result indicates that field value for boolean field "inStock" is seen as "true" : 7.071068 = (MATCH) FunctionQuery(if(bool(inStock),const(10),const(0))), product of: 10.0 = if(bool(inStock)=true,const(10),const(0)) 1.0 = boost 0.70710677 = queryNorm Same behaviour using FunctionQuery via LocalParams syntax : http://localhost:8983/solr/select?q={!func}if%28inStock,10,0%29&debugQuery=true 10.0 = (MATCH) FunctionQuery(if(bool(inStock),const(10),const(0))), product of: 10.0 = if(bool(inStock)=true,const(10),const(0)) 1.0 = boost 1.0 = queryNorm Is that expected ?
