Java Elastic query not returning results

Elastic Stack Elasticsearch
2

Hello!

Just to clarify, this is not the HLRC, this is Spring Data which uses the elasticsearch-java-client underneath. The High Level Rest Client was the old version of the elasticsearch-java-client and is now deprecated.

As we do not maintain the Spring Data library for elasticsearch, we're not the ones suited to provide support in this case.

We could try bypassing Spring and checking if it's a client problem, so here's the query using only the elasticsearch-java-client version 8.16.1:

esClient.search(s -> s
        .query(q -> q
            .bool(b -> b
                .must(
                    TermQuery.of(t -> t
                        .field("abcField.keyword")
                        .value("xyz")
                        .boost(1.0F))._toQuery(),
                    RangeQuery.of(r -> r
                        .date(d -> d
                            .field("timeField")
                            //... 
                        ))._toQuery()
                )
                .boost(1.0F)
            )
        )
, Void.class);

Note that adjust_pure_negative is missing, this is an internal parameter that is passed to Lucene in very specific cases.

One other thing I'd check is whether all versions are matching: which server version are you using? Which Kibana version? Which version of the client does Spring Data uses? I'm suspecting it's at least < 8.15 since it's using deprecated parameters in the range query. If there's severe discrepancy between versions it could be the cause of the issue.

Here is some documentation showing how to setup the client.
