Hi,

I'd like to increase/decrease the scores of the results from a multimatch query with several function scores.

This following code works :

FunctionScoreQueryBuilder functionScoreQuery = QueryBuilders.functionScoreQuery(  
multiMatchQuery,  
ScoreFunctionBuilders.gaussDecayFunction("creationdate", "now", "60d", "30d", 0.5)  
)  
.scoreMode(ScoreMode.MULTIPLY)  
.boostMode(CombineFunction.SUM);

But I have a problem using FilterFunctionBuilder[], I lose the scores of the multi match :

FilterFunctionBuilder[] filterFunctions = {  
new FunctionScoreQueryBuilder.FilterFunctionBuilder(  
multiMatchQuery,  
ScoreFunctionBuilders.gaussDecayFunction("creationdate", "now", "60d", "30d", 0.5)  
)  
};  
FunctionScoreQueryBuilder functionScoreQuery = QueryBuilders.functionScoreQuery(filterFunctions)  
.scoreMode(ScoreMode.MULTIPLY)  
.boostMode(CombineFunction.SUM);

What's wrong please ? Should I use "should" instead of "function score" ?

Thank you

Ok the solution is :

FilterFunctionBuilder[] filterFunctions = {  
new FunctionScoreQueryBuilder.FilterFunctionBuilder(  
ScoreFunctionBuilders.gaussDecayFunction("creationdate", "now", "60d", "30d", 0.5)  
)  
};

FunctionScoreQueryBuilder functionScoreQuery = QueryBuilders.functionScoreQuery(  
multiMatchQuery,  
filterFunctions  
)

Sorry for the confusion
