Just so you know: vocabulary search has been implemented!
Just noticed this now!
Hi JoeOcher. Though it's not a bad idea, I actually think this might be an unwanted addition for search, as it could clutter up the search results if a user just wants to search for all words of a certain suffix to see a pattern in verb conjugation, etc. If you'd like to see all conjugations of a word, you can always search for the root or click on the word after searching to see all forms. In the future we may look into more intelligent search options:)
