While reading an article I got a word called Keyword stemming. Can anyone please tell me what is it?

It is the process of reducing each word to its stem. E.g. "searched", "searches", "searching" all become just the root word (or stem) "search" in a search index.

In terms of websites, this is frequently used for search functionality. I.e. enabling any form of the search term to find all variations of the supplied keyword. It can significantly improve the search experience.

"Stemming" reduces words to their stem, but I think "keyword stemming" goes the other way. Rather than reducing words to their stem, website developers will create longer keywords from the stem, to specifically target different variations of the stem word. – w3d Nov 8 '12 at 11:23
