            Bug ID: 11069
           Summary: increase title ranking in relevance when using
                    QueryWeightFields
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P5 - low
         Component: Searching

when using QueryWeightFields to add ranking on a search without index, the
search actually uses: 
 - rank 1 : Title-cover,ext :  exact title-cover
 - rank 2 : ti,ext : exact title
 - rank 3 : Title-cover,phr : phrase title-cover
 - rank >7 : queries without index
This relevance sets title as phrase in priority and then any index.
I propose to add title as words list before search on any index, so that
records with all searched terms in title, even not well ordered, are more
relevant.
