When testing the ExternalIndex Examine index in the Settings tab in the backoffice you can search for terms and get results. First, I wonder if there's a way to get results with "close" spelling. For example, searching for

programing

should give results for

programming

. Is this functionality available, and if so, are you supposed to create your own Examine search queries, simply refer to Examine/Lucene documentation? Second I also wonder about "similar" terms, for example the word

performance

could produce results that contain the word

perform

even though it's not a simple spelling mistake. Same question there - is it possible? If so, how?
