I'm new to Solr and I'm not fully aware of what it can and can't do.
I'm trying to build a system where the documents will have a field with a string value x, and I want to efficiently query those documents against some string y, where x is a substring of y. It's like the opposite of the usual substring matching queries.
Is this possible to do efficiently in Solr? If not, does limiting x to be a single word and y to only consists of few words helps in anyway?
