Multiple threads with same topic is one of the major reasons of spamming on this forum,  majority of the members don't use "search" before creating a new thread.

I am wondering that if admins can add an automatic "search" feature in the creation process of new thread, it can help to minimize the amount of similar threads.
Like if i have to post a new thread with subject " Honesty is the best policy" i have to go through an additional step when i click "post", the forum automatically search my subject in that section and display topics with almost same subject, so i can check if my topic already exists or not.
