Dear Zhang,
Sorry for my tardiness in replying. I have extremely slow e-mail search times. Almost 2minutes to search record of 20,000 emails. Thats why I am so desperately trying to get a solution for this.
This is my search performance below. I will do more testing to figure out why is it behaving like this.
Thanks
