Looking for Glossary-Plugin… but the other way round

Hello everyone,

I’m working on a project for a university prof, who would like to present all his material online. By doing this, he would also like to create the possibility of a fast-access to certain topics. Meaning: He writes something about “determination” on one page, and on another page, and even on one page more. If any visitor now wants to know anything about “determination” he would click on the term “determination” on one of the three pages and will be redirected to a glossary, where the three pages are listed that contain the word “determination”. (Like an index of the end of a book…)

As you see it’s pretty much like a search-function, only without the need to actually search for something but with a list of words which are explained. The important thing is not to create this list (a plugin like Pages Autolink would do the trick here), but to automatically create sites that show all posts containing a certain term.

Thanks for your time so far 😉
Any help is very much appreciated!
