Make searching for items more flexible

When I am searching for records (usually those with high volume such as ideas or features), the search limits me to "exact match" on whatever text I enter. For example, let's say I know there is an idea that contains the words 'address' and 'charge' in the title but not necessarily together. If I put in those two words, I receive the response that no records match my search. Ideally, I would be able to put in a string of text and indicate whether I want to search an EXACT MATCH of that text string or if I just want to search records that CONTAIN those words.
