[search_phase_execution_exception] without a root reason

Elastic Stack Elasticsearch

Correct, this is what will be logged by default, if the exception is not handled. By catching the ElasticsearchException you can customize the depth of error you can log, for example:

public static void main(String[] args) throws IOException {

        try (
            ElasticsearchClient client = ElasticsearchClient.of(e -> e
                .host("host")
                .apiKey("apikey"))) {

            client.search(s -> s
                .index("test")
                .query(q -> q
                    .queryString(qs -> qs
                        .query("\"test")))
            );
        } catch (ElasticsearchException e) {
            System.out.println(e.error());
        }
    }

will print:

ErrorCause: {"phase":"query","failed_shards":[{"shard":0,"index":"test","node":"uLsAhJL1SG6fVTHEDpVP7w","reason":{"type":"query_shard_exception","reason":"Failed to parse query [\"test]","index_uuid":"7FHHQQkBREG2GsOemvrlyw","index":"test","caused_by":{"type":"parse_exception","reason":"Cannot parse '\"test': Lexical error at line 1, column 6.

which is the same thing you’d see in Kibana :slight_smile:
