If a term is present only inside markup, for example
{{foo}} I have to search for "
{{foo}}" rather than just "foo" in order to get all appropriate results. This makes searching for code-like terms more difficult than necessary.

In other words, I'm not sure markup should be significant.

(Can't figure out the appropriate escaping to make it show up properly. The search term should be curly-curly-foo-close-close, and the one I have to use is the same, but quoted.)
