Elasticsearch查询:增强特定字段

Question

我正在使用Elasticsearch 2.4.3，并希望在我的查询中增加特定的字段。这个是可能的吗？我只知道如何提指数。

欢迎光临！

制图：

"firstName":{"type":"string",
     "analyzer":"customNGram"
},
"lastName":{
     "type":"string",
     "analyzer":"customNGram"
},
"note":{
     "type":"string",
     "analyzer":"customNGram"
}

查询(Java )：

    QueryBuilder qb = new BoolQueryBuilder()
        .must(QueryBuilders.matchQuery("_all", term)
                .analyzer("atsCustomSearchAnalyzer")
                .operator(Operator.AND));

    SearchRequestBuilder searchRequestBuilder = elasticsearchClient.prepareSearch("persons", "activities").setTypes("person", "activity")
            .setQuery(qb)
            .addHighlightedField("*").setHighlighterRequireFieldMatch(false)
            .setHighlighterOrder("score")
            .setHighlighterFragmentSize(150)
            .setHighlighterForceSource(true)
            .setSize(100)
            .addIndexBoost("persons", 200)
            .setFrom(offset); 

    return searchRequestBuilder.execute().get();

如果将匹配查询拆分为匹配单个字段(如使用多匹配查询(https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html) )，则可以增加您喜欢的字段。所以，就像：

QueryBuilder qb = new BoolQueryBuilder()
    .must(QueryBuilders.multiMatchQuery(term, "firstName^3",
    "lastName^3", "note")
            .analyzer("atsCustomSearchAnalyzer")
            .operator(Operator.AND));

相对于备注字段，应该将firstName和lastName提高3倍。
