Subject Re: Tracking that all query terms are matched in one document
Date Tue, 05 Dec 2017 07:04:35 GMT
For example like this:

BooleanQuery.Builder expected = new BooleanQuery.Builder();

Query param_vendor = new BoostQuery(new ConstantScoreQuery(new
TermQuery(new Term("param_vendor", queryStr))), 5f);
Query param_model = new BoostQuery(new ConstantScoreQuery(new
TermQuery(new Term("param_model", queryStr))), 5f);
Query param_value = new BoostQuery(new ConstantScoreQuery(new
TermQuery(new Term("param_value", queryStr))), 3f);
Query param_name = new BoostQuery(new ConstantScoreQuery(new
TermQuery(new Term("param_name", queryStr))), 4f);

BooleanQuery bq = expected
        .add(param_vendor, BooleanClause.Occur.SHOULD)
        .add(param_model, BooleanClause.Occur.SHOULD)
        .add(param_value, BooleanClause.Occur.SHOULD)
        .add(param_name, BooleanClause.Occur.SHOULD)
        .setMinimumNumberShouldMatch(1)
        .build();

return new BoostQuery(bq, queryBoost);
