search results don't make sense

an example. when i type the word “grant” into the search field, i expect to see the top results to come from page and blog titles, but instead, the top result is a page title, but the next result with the word “grant” in the title is tenth on the list.

how do i get the order of the results to be search word in titles as the first results, followed by search word in content as the later results?
