Webinator is based on Texis and as such it shares its text query abilities with all of Thunderstone's products. Throughout our documentation you will see references to Metamorph or Texis. This is because all of our products share a common text query language. This document provides only a brief overview of this language.
If you'd like to know more see the online manual at http://docs.thunderstone.com/site/texisman/link_mmq.html .
