Search by Words in Page Titles Only

Just wondering how can I get the plugin to only search for words within page titles rather than every single page that contains that word?

For example if the user searches for “London” I only want them to see the page named “The London Page” in the results.

Currently because I have the word London in my footer, the search results show every single page.

Thanks.
