Narrowing the scope of keyword matching to <h1>

[SuxinL]

From my experience, the keyword matching seems to search the whole page, which is too rigid. If there is a matching in a side bar or other irrelevant locations, the whole page is blocked. If the main article just mentions the keyword once but does not focus on it, the article is blocked.

So I think that it makes sense to provide an option to narrow the search scope to the topic, i.e, h1 header. I understand that many pages embed the topic in its URL, but there are many others using random IDs.
