Hi Tomas Here is what I was trying to give.
http://localhost:8085/apache-solr-3.3.0/select?indent=on&version=2.2&defType=dismax&q=scientific&bq=Field1:[20%20TO%2030] ^10&start=0&rows=30&qf=text&fl=Field1,docid&debugQuery=on Over here, I was trying to change the range of Field1, keeping everything else intact. Here are my observations: 1) The number of results found remain intact. Only that the order of the results varies. 2) The boost factor (10) does not seem to throw any influence at all. Here is what the debugQuery says: <str name="parsedquery">+DisjunctionMaxQuery((text:scientif)) () Field1:[20.0 TO 30.0]^10.0</str> <str name="parsedquery_toString">+(text:scientif) () Field1:[20.0 TO 30.0]^10.0</str> >From these, it seems like its just filtering the results based on the Field1 values, rather than performing a Boost Query.
