> Usually, search results are sorted by their score (how well the document
> matched the query), but it is common to need to support the sorting of
> supplied data too.
> Boosting affects the scores of matching documents in order to affect ranking
> in score-sorted search results. Providing a boost value, whether at the
> document or field level, is optional.
> When the results are returned with scores, we want to be able to only "keep"
> results that are above some score (i.e. results of a certain quality only).
> Is it possible to do this when the returned subset could be anything?
> I ask because it seems like on some queries a score of say 0.008 is resulting
> in a decent match, whereas other queries a higher score results in a poor
> match.
> I have written pseudo code to accomplish what I said
> double scoreLimit = 0.75 #For example
> searchResults = new Results[numberOfResults];
> boolean lastScore=false;
> solrSearchResults = Calling Solr Engine.
> for( Result result : solrSearchResults) {
> if (lastScore != false && result.score/lastScore<scoreLimit) break;
> lastScore = result.score;
> Adding new result to searchResults array
