For my understanding there is no such thing like a feature that kills a specific query that would cause an OOM. Either in Solr or in general in any other search engine. I suggest you start investigating if Solr memory is enough for the kind of queries you have, then try to understand what query is dangerous (in terms of memory allocation) and why.
