Please try it out and report back. You’ll find that the “qf” param will only ever produce matches for single tokens, split on whitespace by the query parser. You are right that the pf solution is only good for boosting exact matches of a field which should also match partially, and Derek wants it to match phrase search but not partial search. This gets a bit trickier. You can fix it partially by rewriting the query into a normal dismax OR’ed with a phrase match on the exact field. But if you expect a sub-phrase to trigger the match, e.g. q=black dvd bracket, where black should match partially in the qfs and “dvd bracket” should match exact in the exact field, then it gets more tricky. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com > 29. jan. 2016 kl. 15.50 skrev Alessandro Benedetti <abenede...@apache.org>: > > Still not following. > Why you would like to use pf for exact search ( which is different from > phrase search) ? > Let's summarise : > > pf > <https://cwiki.apache.org/confluence/display/solr/The+DisMax+Query+Parser#TheDisMaxQueryParser-Thepf(PhraseFields)Parameter> > > Phrase Fields: boosts the score of documents in cases where all of the > terms in the q parameter appear in close proximity. > > pf is for very specific use cases, when you want to boost phrase searches > in a set of fields, to boost those documents up. > In our case we want to boost exact search ( not phrase search). > Simply adding the copy field not tokenised with the related boost to the > qf list should be fine. > Am I missing something ? > > On 29 January 2016 at 10:33, Jan Høydahl <jan....@cominvent.com> wrote: > >> Hi >> >> Did you try?
