HI Mikhail, We're using 4.7.1. This means I can't stop the search. I think this is mandatory feature.

FWIW, in 4.x timeallowed is checked only while documents are collected, and in 5 it's also checked during query expansion (see http://lucidworks.com/blog/solr-5-0/ now cut-offs requests <https://issues.apache.org/jira/browse/SOLR-5986> during the query-expansion stage as well ). however I'm not sure it has place (long query expansion) with hon-synonyms.
