bad search results

Website URL: http://partythemesforbirthday.com
URL to page in question: all

when using a phrase or title like "my little pony" I get unacceptable results that include products who contain any word i.e. my, little, pony, and my little pony.

how exactly can i fix this so that I do not get pages of results but only the full phrase result.
I as the webmaster can of course surround the phrase my little pony with quotes and than I get the desired results, however the average visitor will not do that and sees the page with irrelevant results and leaves my site frustrated.

looking at the first line of the search fields can I replace 'word' with 'phrase' ?
