Currently, the search bar in the forum is so simple and even can't find topics until you enter the full word.
my forum is in "Persian" language and sometimes users enter English words in title. When other users want to search, They have to enter the full of word to find that topic.
For example, if I have word "Wordpress" in title, and user insert "Wordpres" (just less an S character"), Search feature can't find this topic.
All i want to say is enable words wildcard for search bar, And if it will use more recourse of server just add an option to disable/enable it from admin panel.
Sometimes my users can't find topics only because they don't know they have to type exactly that word.
