如何使用RestHighLevelClient查找具有特定字段的文档包含字符串

Question

So, I can make simple via url:

<elastic_host>/indexname/_search?pretty=true&q=text:*str*

I want to do the same with RestHighLevelClient, but it dosn't work:

 SearchRequest searchRequest = new SearchRequest(indexName);
    searchRequest.types(INDEX_TYPE);
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    QueryBuilder queryBuilder = QueryBuilders.matchQuery(IMAGE_TEXT_FIELD_NAME, "*str*" );
    searchSourceBuilder.query(queryBuilder);
    searchRequest.source(searchSourceBuilder);
SearchResponse response = client.search(searchRequest, RequestOptions.DEFAULT);

Answer 1

The equivalent query is not a match query but a query_string query, so you can replace the following line

QueryBuilder queryBuilder = QueryBuilders.matchQuery(IMAGE_TEXT_FIELD_NAME, "*str*" );

by this one

QueryBuilder queryBuilder = QueryBuilders.queryStringQuery("*str*").field(IMAGE_TEXT_FIELD_NAME);
