|| We have defined the Category:Keywords, where keywords to various topics are listed. I'd like to relate the keywords to each other, like in a Category Tree, but first need to have a "same as" or "similar to" expression.
Example: "GSM" and "2G" are two words for the same mobile standard, but currently separated. I would treat them as "similar to".
Now: A user wants to search all "lectures, courses, thesis, people" for "2G" knowledge. He would find 2G (currently no entry), but should have been redirected to "GSM", where people. lectures and thesis related to the topic are presented
