Cancelling Search Request & Search Query Timeout

Elastic Stack Elasticsearch
1

Hi Team,

We use the following statements (only partial) to get the search response -

SearchRequestBuilder builder = null;
SearchResponse res= builder .execute().actionGet();

Can we cancel the above search request!

Also we use the following statement to set the query timeout value in the SearchRequestBuilder instance -

SearchRequestBuilder builder= TransportClient.prepareSearch().setTimeout(...);

Here TransportClient has already been initialized. We set the timeout to 1 minutes. It happen sometimes that we don't get the response in 1 minutes and even query is not timed out, that is query is executing on ES server. We don't get any exception either. Can someone please explain the scenarios when query will be timed out or not timed out! Do we need to set some other way.

We have a GWT web application and when user don't get response in a certain time he started to get impatient and hit the submit button again. For this we have decided to disable the submit button and enable it only when we get back the response. But in cases where query doesn't return any response or throw exceptions, in certain time user waits longer & longer.

Please suggest.

Thanks.

The search request cannot be cancelled. From my understanding of the code,
the timeout value is used only as a parameter to the TimeLimitingCollector
wrapper around elasticsearch's facet collectors. There have been other
discussion regarding long queries not respecting the timeout value.

Note that actionGet() can be replaced by a time-limited version, for example

SearchResponse response = builder.execute().actionGet()

-->

SearchResponse response = builder.execute().actionGet(1, TimeUnit.MINUTES)

As said, this does not stop a running query execution, but it returns to
the requester if the execution times out with an
org.elasticsearch.ElasticSearchInterruptedException
