> Hi, > > For the sake of simplicity, I have an index with docs containing the > following fields: > > Title > Description > Author > > Some searches will obviously be saturated by docs from any given > author if they've simply written more. > > I'd like to give a negative boost to these matches, there-by making > sure that 1 Author doesn't saturate the results just because they've > written 500 documents, compared to others who may have only written 2-3 > documents. > > The actual author value doesn't matter, I just want to bring down the > score of docs by any common author to give more varied results. > > What's the easiest approach for this, and is it even possible at query > time? I could do this at index time but would prefer a Solr solution. > > Solr 3.4 using edismax handler > > Thanks, > Rob
