Elasticsearch搜索Java API

Question

我有一个ElasticSearch的工作查询,但是我在使用ElasticSearch的Java API执行相同的查询时遇到了问题.

如何使用ElasticSearch的Java API表达下面的查询？

http://localhost:9200/mongoindex/files/_search?q=anyword&fields=file.file

Answer 1

这种类型的查询使用query_string查询.java代码应该如下所示:

SearchRequestBuilder searchRequestBuilder = new SearchRequestBuilder(client);
searchRequestBuilder.setIndices("mongoindex");
searchRequestBuilder.setTypes("files");
QueryStringQueryBuilder queryStringQueryBuilder = new QueryStringQueryBuilder("anyword");
queryStringQueryBuilder.field("file.file");
searchRequestBuilder.setQuery(queryStringQueryBuilder);
SearchResponse response = searchRequestBuilder.execute().actionGet();
