Meta tags use in Drupal Search

Hi, I want to get my meta tags included in my normal Drupal site search but am unsure how to do this.

The issue I have is a keyword is commonly misspelt without a space ie 'abcdef' rather than 'abc def' and, because we spell it correctly in the node body, search doesn't pick it up. As a soulution we put both the correct and incorrect spellings in the meta keywords for the affected nodes and were hopeful that search would pick it up, but it doesn't.

Any help is greatly appreciated.
