Similar question check is one of the best features in Q2A. But unfortunaltely on my website this feature is not checking all existing questions. If I ask a question the 5 set questions show all the time. In very few cases it checks all the questions and shows really similar questions.
Because of this problem I have set similarity check to be "narrower". Moreover I have also reindexed content in stats section so that similar content should catch all the content. But all of my tries are of no use.
Can something be done in this regard?
