Briefly, this error occurs when a query or operation in Elasticsearch takes longer than the set timeout limit. This could be due to heavy data load, inefficient queries, or insufficient resources. To resolve this, you can increase the timeout limit, optimize your queries for efficiency, or scale up your Elasticsearch cluster to handle more data. Additionally, consider implementing pagination to break down large data retrieval into smaller, manageable chunks.

Log Context

Log “Time exceeded” class name is QueryPhase.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 queryResult.terminatedEarly(true);
 } catch (TimeExceededException e) {
 assert timeoutSet : "TimeExceededException thrown even though timeout wasn't set";
 if (searchContext.request().allowPartialSearchResults() == false) {
 // Can't rethrow TimeExceededException because not serializable
 throw new QueryPhaseExecutionException(searchContext.shardTarget(); "Time exceeded");
 }
 queryResult.searchTimedOut(true);
 }
 if (searchContext.terminateAfter() != SearchContext.DEFAULT_TERMINATE_AFTER && queryResult.terminatedEarly() == null) {
 queryResult.terminatedEarly(false);
