This recognizer works in a similar way to the Entity Recognizer in the sense that looks up sequences of tokens in a dictionary to match the text being processed. The difference is that it will also include in the matching text N tokens to the right and/or left of the original matched text.
Group tokens in its own tag ( type=boolean | default=false | optional ) - When true, the recognizer will create internal tags to tag the left part, the matched text and the right part
Matched tokens tagname ( type=string | default=_matchedTokens_ | optional ) - Internal Tag name for the matched text portion
Left tokens tag name ( type=string | default=_leftTokens_ | optional ) - Internal Tag name for the tokens at the left of the matched text
Right tokens tag name ( type=string | default=_rightTokens_ | optional ) - Internal Tag name for the tokens at the right of the matched text

More settings could be displayed in the same dialog, it varies per recognizer.
