Investigate Mongodb full text index on test output

The Advance search feature searches all test output in DB. It takes really long time to return the result. We should look into a more efficient way of searching (i.e., Mongodb full-text index)

Start by tracing the Advance search path that searches test output, then review MongoDB's text-index documentation and the linked examples. Determine where the search is implemented and how its current response time is measured; done should mean an agreed, tested approach that makes these searches more efficient.
