Keywords we use are tricky things, we all have our own, so does the search engines. The search engines contently work on figuring out what we mean by certain keyword, and it is difficult for them to understand the non native English speakers. So I thought may be I should look around to see how these keywords I use to describe are related with other keywords, did a little search,

And I came across this Semantic search engine, which gives a summery of the related word for search which I find very interesting, maybe you will too
