Search by included words rather than whole phrase

Hello! We love Hudu, and one thing we think might make it more user-friendly is changing the search function to work based on included key words, rather than looking for a complete phrase.

Example:

Search 'password office 365' should return the article 'How to change your Office 365 password'. At the moment, you have to type the phrase as it appears in the article title, 'office 365 password' in order for the result to be found.
