Hi Shawn, We checked this option and it didn't solve our problem. We're using https://github.com/healthonnet/hon-lucene-synonyms for query based synonyms. While running query with high number of words that have high number of synonyms the query got stuck and solr memory is exhausted. We tried to use this parameter suggested by you however it didn't stop the query and solve the issue.
Please let me know if there is other option to tackle it. Today it might be high number of words that cause the issue and tomorrow it might be other something wrong. We can't rely only on user input check. Thank you in advance.

The "timeAllowed" parameter can abort a query that takes too long in certain phases of the query. In recent months, Solr has been modified so that timeAllowed will take effect during more query phases. It is not a perfect solution, but it can be better than nothing. http://wiki.apache.org/solr/CommonQueryParameters#timeAllowed Be aware that sometimes legitimate queries will be slow, and using timeAllowed may cause those queries to fail. Thanks, Shawn
