I think that will be useful if you add an option to filter some words that are irrelevant for SEO purposes, I mean short words that Google and other search engines don't have in account when you make a search, words like: "to", "the", "of", and so on.
AFAIK these type of words aren't relevant. Is this really true?
And just in case that you add this option... it will have as a implicance a higher CPU load?
Thank you!
