Java HighLevelRestClient search problem

Elastic Stack Elasticsearch
1

I am new to ElasticSearch and have been trying to write Java EE to bring data in from an Informal DB and then run user searches on it. I have been able to get the indexing to work and am able to retrieve a specific indexed document via 'GET /index/type/id' type structure, but when I try to search for a string I get various errors. Currently, I am running on a local instance of ElasticSearch ver6.0.0 on my MacBook Pro. I also have a local instance of Kibana running and am able to retrieve data within it.

My code looks like this:

  public SearchResponse searchRecord(String searchString ) throws RadarException {
        
        SearchRequest searchRequest = new SearchRequest(); 
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); 
        searchSourceBuilder.query(QueryBuilders.queryStringQuery(searchString)
                                                    .lenient(Boolean.TRUE)
                                                    .autoGenerateSynonymsPhraseQuery(Boolean.FALSE)); 
        searchRequest.source(searchSourceBuilder); 
        searchRequest.types("njcrash");   //put in to see if specifying a type would fix error when type was not specifed

        SearchResponse searchResponse;
        
        try {
            searchResponse = restClient.search(searchRequest);

        } catch (Throwable t) {
            throw new RadarException("Search faild: " + searchRequest.source().toString(), t);
        }

I get the following error (just a segment from the stack dump):

 [type=parsing_exception, reason=[query_string] query does not support [auto_generate_synonyms_phrase_query]]]

The following is the generated search string that was executed ('searchRequest.source()'):

{"query":{"query_string":{"query":"JULIE","fields":[],"type":"best_fields","default_operator":"or","max_determinized_states":10000,"enable_position_increments":true,"fuzziness":"AUTO","fuzzy_prefix_length":0,"fuzzy_max_expansions":50,"phrase_slop":0,"lenient":true,"escape":false,"auto_generate_synonyms_phrase_query":false,"fuzzy_transpositions":true,"boost":1.0}}}

My problem/question is .. How do I get the QueryBuilders.queryStringQuery(string) to STOP inserting the 'auto_generate_sysnonyms_phrase_query' parameter since query_string doesn't support it?

Oh, I just noticed the code segment was from after I tried making the auto_generate_synonyms_phrase_query false... prior to this the parameter was NOT present in the code and it added it anyways set to TRUE.

Most likely you are using a version of the HLRestClient which os totally different from the server. Like HLClient 5 with Server 6 or HLClient 6 with server 5.

Hi, Hope you had a good holiday weekend..

I have checked my code and have brought in the 6.2.2 High Level client:
compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.2.2'
and
compile 'org.elasticsearch.client:elasticsearch-rest-client:6.2.2'

and the server was the 6.0.0 build:
elasticsearch-6.0.0.tar

The server is supposed to be forward compatible, right?

This should work. I'd use that same server version though

Okay.. I have downloaded the latest 6.2.3 server and High Level and Low level clients 6.2.3..

Removed the .autoGenerateSynonymsPhraseQuery parameter from the search builder as shown below:

public SearchResponse searchRecord(String searchString ) throws RadarException {

SearchRequest searchRequest = new SearchRequest(); 
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); 
searchSourceBuilder.query(QueryBuilders.queryStringQuery(searchString)
                                            .lenient(Boolean.TRUE));
                                     //       .autoGenerateSynonymsPhraseQuery(Boolean.FALSE)); 
searchRequest.source(searchSourceBuilder); 
searchRequest.types("njcrash");   //put in to see if specifying a type would fix error when type was not specifed

SearchResponse searchResponse;

try {
    searchResponse = restClient.search(searchRequest);

} catch (Throwable t) {
    throw new RadarException("Search faild: " + searchRequest.source().toString(), t);
}

return searchResponse;

}

and yet it still adds it into the built search command..

...Exception: Search faild: {"query":{"query_string":{"query":"JULIE","fields":[],"type":"best_fields","default_operator":"or","max_determinized_states":10000,"enable_position_increments":true,"fuzziness":"AUTO","fuzzy_prefix_length":0,"fuzzy_max_expansions":50,"phrase_slop":0,"lenient":true,"escape":false,"auto_generate_synonyms_phrase_query":true,"fuzzy_transpositions":true,"boost":1.0}}}

Any other ideas?

OK, found it... I would call it a bug, but maybe I don't understand something... If you comment out the statement in the above code segment:
searchRequest.types("njcrash");

Then it does not add the auto_generate_synonyms_phrase_query to the searchRequest. It seems like you should be able to restrict the search to only a certain type with this parameter but maybe that is done another way.

Worth opening an issue then and link to this thread?
