Currently I am working on a part of a wikimirror project that involves
doing a search in wikipedia and retrieving snippet of text with searched
terms being highlighted.
I would like to improve what I am doing at the moment by highlighting also
different forms of a given word.
For example if user types in: 'playing' I would also highlight play, plays,
played and so on.
In wikipedia this already works like this:
https://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=def…
I would like to ask what technics (plugins, libraries, extensions)
wikipedia uses to do this type of highlighting.
I would appreciate any answer.
