Spring Data api (Containing or startwith) not working with SPACE which has wildcard

问题

I am using Elastic Search with Spring Data .

I have a simple method in repository:

findByUserNameContaining("a b");

This method not giving expecting result because of SPACE.

Error getting:

"Cannot constructQuery '"a b"'. Use expression or multiple clauses instead." EXCEPTION="org.springframework.dao.InvalidDataAccessApiUsageException: Cannot constructQuery '"a b"'. Use expression or multiple clauses instead.

For stopping creation of multiple tokens because of Space. I have mapping:

"userName": {
    "type": "string",
    "index": "not_analyzed"
},

I am totally surprised that I am getting this issue after "index": "not_analyzed" in mapping .

Please help me. Thanks in advance!

Actually Spring data apis (containing or startWith) does not work with space in String . I have implemented same with Elastic core api.

NativeSearchQueryBuilder aNativeSearchQueryBuilder = new NativeSearchQueryBuilder();
        aNativeSearchQueryBuilder.withIndices(indexName).withTypes(type);
        final BoolQueryBuilder aQuery = new BoolQueryBuilder();

            aQuery.must(QueryBuilders.queryStringQuery("a b").defaultField("UserName"));

NativeSearchQuery nativeSearchQuery = aNativeSearchQueryBuilder.withQuery(aQuery).build();
        List<Object> aDatas = elasticsearchTemplate.queryForList(nativeSearchQuery, Object.class);

You have to mask the spaces:

findByUserNameContaining("a\\ b");
