Example 1 with FieldValueFactorFunction

use of org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction in project elasticsearch by elastic.

the class DiversifiedSamplerTests method testCase.

private void testCase(IndexSearcher indexSearcher, MappedFieldType genreFieldType, String executionHint, Consumer<InternalSampler> verify) throws IOException {
    MappedFieldType idFieldType = new KeywordFieldMapper.KeywordFieldType();
    idFieldType.setName("id");
    idFieldType.setHasDocValues(true);
    SortedNumericDVIndexFieldData fieldData = new SortedNumericDVIndexFieldData(new Index("index", "index"), "price", IndexNumericFieldData.NumericType.DOUBLE);
    FunctionScoreQuery query = new FunctionScoreQuery(new MatchAllDocsQuery(), new FieldValueFactorFunction("price", 1, FieldValueFactorFunction.Modifier.RECIPROCAL, null, fieldData));
    DiversifiedAggregationBuilder builder = new DiversifiedAggregationBuilder("_name").field(genreFieldType.name()).executionHint(executionHint).subAggregation(new TermsAggregationBuilder("terms", null).field("id"));
    InternalSampler result = search(indexSearcher, query, builder, genreFieldType, idFieldType);
    verify.accept(result);
}

Example 2 with FieldValueFactorFunction

use of org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction in project elasticsearch by elastic.
