java - 2带有查询的过滤器在ElasticSearch中不起作用，Java

Question

这是我的旧代码，可以正常工作

qb = QueryBuilders.queryString(query.replaceAll(" ", " OR ").replaceAll(",", " AND ").replaceAll("!", " NOT "));
FilterBuilder fb = FilterBuilders.andFilter(FilterBuilders.rangeFilter("Experiance").from(smonth).to(emonth));
 FilteredQueryBuilder fqBuilder = QueryBuilders.filteredQuery(qb, fb);

org.elasticsearch.action.search.SearchResponse searchHits =  node.client()
                .prepareSearch(name)                
                .setQuery(fqBuilder)

在这段代码中，我正在搜索在月和月之间经历过的数据。

现在，我需要在搜索中添加更多过滤器，因此我转到“NativeSearchQueryBuilder”。修改后，我写这段代码:

qb = QueryBuilders.queryString(query.replaceAll(" ", " OR ").replaceAll(",", " AND ").replaceAll("!", " NOT "));
FilterBuilder fb = FilterBuilders.andFilter(FilterBuilders.rangeFilter("Experiance").from(smonth).to(emonth));
NativeSearchQueryBuilder builder = new NativeSearchQueryBuilder();
        builder.withQuery(qb);
        AndFilterBuilder filters = null;
        filters = new AndFilterBuilder(fb);
       filters.add(FilterBuilders.andFilter(FilterBuilders.boolFilter().must(FilterBuilders.termFilter("providedZipcode", zipcode))));  //third filter
        builder.withFilter(filters);


org.elasticsearch.action.search.SearchResponse searchHits =  node.client()
                .prepareSearch(name)                
                .setQuery(builder.build().getQuery());

但是，当我搜索然后筛选器不起作用。我没有根据经验和邮政编码获得数据。

Answer 1

得到它了。

我们可以使用setPostFilter

https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/search.html

org.elasticsearch.action.search.SearchResponse searchHits =  node.client()
                .prepareSearch(name)
              //  .setIndices(name)
                 .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
                .setQuery(fqBuilder)
                .setPostFilter(FilterBuilders.andFilter(FilterBuilders.boolFilter().must(FilterBuilders.termFilter("providedZipcode", zipcode))));  // Filter

但是我还有另一个问题。如果我没有通过邮政编码，则不会显示数据。如果我不通过任何邮政编码，我想获取所有数据。
