Hello So, from what I've picked up so far: FST only matches from the beginning of the input, but can handle spelling errors and do stemming. AnalyzingInfix can't handle spelling errors or stemming but can match from the middle of the string. (Is there anyway to achieve both of the functionalities above, if need be?) Performance-wise, FST's are faster and more compact?
