Search diagnosis by three letters

It would be helpful if you could enter the first three letters of several words in a diagnosis and be able to search that way. this is how most other EHRs work. If I type in the first few letters and then move on to another word that helps specify it then the search comes up with nothing. Sometimes things are worded as depression, or depressive and it's easier to just be able to search for maj dep dis rec than it is to type out everything in the diagnosis.
