Both the Main Equivalence File and the User Equivalence File include a provision for "back referencing". That is, where a word is stored as the equivalence to another root entry, there is an inherent connection "backwards" to the root, when that equivalence is entered as a keyword (root) on the Query Line.
For example, imagine the following Equivalence File entry for the root
A&R,automation,robotics,automation and robotics
Metamorph, and so therefore Texis, knows when you enter
robotics" as a root word in a query, that it should back
search and associate it with "
A&R". Therefore, when
robotics" is used as a keyword, "
A&R" will be
automatically associated as one of its equivalences.
Back referencing means that the following association is implicitly understood, and need not be separately entered:
Such automatic back searching capability exponentially increases the density of association and connection within the Equivalence File and User Equivalence File.
