Subject Re: any example on FunctionScoreQuery since Field.setBoost is deprecated with Lucene 6.6.0
Date Wed, 01 Aug 2018 16:10:37 GMT
i have one MultiFieldQueryParser based Query and one BooleanQuery with 
dynamic number of TermQuery's.

i dont have SortField objects. Are there examples with the above query 
types please?

Best regards
