Ask HN: Can HN add more precise search filters?

I wanted to search for "Who wants to be hired?" threads only, but the search always includes "Who is hiring?" threads, because those include the string "Who wants to be hired?" with links to the corresponding threads.

So I get those returned as well, effectively doubling the number of results, half of them irrelevant.

Current search filters only allow to filter by "Stories" or "Comments".

Desired solution: Add another filter "Title only" to exclude searching the OP post or comments for (partially) matching strings.

This seems simple to implement, and would also be a big win performance wise, since the search space is at least an order of magnitude smaller, given the fact that the actual posts/comments themselves are much longer than titles.
