Narrow

Explanation:

Typically, when you do a search engine search, the search will yield results with all or some of the words you enter into the search bar.  For instance, if you search for house in the mountains, your results may include some or all of those words and appear in any order throughout the site/document--some results would only have the word house while some results would only have the word mountains.  Thus, the results will be quite broad. To narrow things down a bit, one should use quotation marks around words as this will yield results with the specific word or phrase in the exact order (and with all content) things appear within the quotation marks.
