We have one specific user who when using the search facitity doesn't find certain things. He is generally expecting/knows there to be more files in existence so opens a new search window and performs the same search. Every single time he will get a different set of results. There is no particular set of parameters that will start this happening. The user will suspect that the information returned is not complete so starts a new search window and runs the same search again and normally gets more files returned.
This, in the first instance, is very annoying, especially when you can't trust what the search is telling you.
Our VAR has drawn a blank.
Has anyone else seen this behaviour? If so how did they resolve it?
