How to use StringQuery in Elasticsearch Spring Data

Question

I want to expose flexible REST service which allows client to perform any query. Similar to elasticsearch API:

http://localhost:9200/blog/post/_search?q=user:dilbert

I found ElasticsearchTemplate and it's method queryForList(StringQuery query, Class clazz). It seems to fit for my purpose.

@RequestMapping(value = "/search", method = RequestMethod.GET)
public List<DynamicEntity> findAllBySearch(@RequestParam("query") String query) {
    return elasticsearchTemplate.queryForList(new StringQuery(query), DynamicEntity.class);
}

But I don't know how to construct the query. I wasn't able to find documentation on this. I tried to guess it with no success. For example:

http://localhost:8080/dynamic/search?query={"query":{"className":"invoice"}}

className is an attribute of DynamicEntity.

I get following error:

org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [dfs], all shards failed; shardFailures {[feu_3VGkTgKKUziW19mXUQ][dynamic][3]: SearchParseException[[dynamic][3]: from[0],size[10]: Parse Failure [Failed to parse source [{"from":0,"size":10,"query_binary":"eyJxdWVyeSI6eyJjbGFzc05hbWUiOiJpbnZvaWNlIn19"}]]]; nested: QueryParsingException[[dynamic] No query registered for [query]]; }{[feu_3VGkTgKKUziW19mXUQ][dynamic][4]: SearchParseException[[dynamic][4]: from[0],size[10]: Parse Failure [Failed to parse source [{"from":0,"size":10,"query_binary":"eyJxdWVyeSI6eyJjbGFzc05hbWUiOiJpbnZvaWNlIn19"}]]]; nested: QueryParsingException[[dynamic] No query registered for [query]]; }{[feu_3VGkTgKKUziW19mXUQ][dynamic][1]: SearchParseException[[dynamic][1]: from[0],size[10]: Parse Failure [Failed to parse source [{"from":0,"size":10,"query_binary":"eyJxdWVyeSI6eyJjbGFzc05hbWUiOiJpbnZvaWNlIn19"}]]]; nested: QueryParsingException[[dynamic] No query registered for [query]]; }{[feu_3VGkTgKKUziW19mXUQ][dynamic][2]: SearchParseException[[dynamic][2]: from[0],size[10]: Parse Failure [Failed to parse source [{"from":0,"size":10,"query_binary":"eyJxdWVyeSI6eyJjbGFzc05hbWUiOiJpbnZvaWNlIn19"}]]]; nested: QueryParsingException[[dynamic] No query registered for [query]]; }{[feu_3VGkTgKKUziW19mXUQ][dynamic][0]: SearchParseException[[dynamic][0]: from[0],size[10]: Parse Failure [Failed to parse source [{"from":0,"size":10,"query_binary":"eyJxdWVyeSI6eyJjbGFzc05hbWUiOiJpbnZvaWNlIn19"}]]]; nested: QueryParsingException[[dynamic] No query registered for [query]]; }

Im I using right method? How to construct valid query? I don't want to use any builder classes because the query should be constructed on client in JavaScript.

Your sample query is not valid (i.e. No query registered for [query]), can you try query={"term":{"className":"invoice"}} instead (i.e. using term instead of query)? — Val

It worked! Thank you very much. Do you want to put this as an answer for the question? — ziri

According to the error you posted, your sample query is not valid (i.e. No query registered for [query]).

You should use this instead (i.e. using term instead of query):

query={"term":{"className":"invoice"}}
