Searching multiple keywords in Outlook using advanced find/query builder - results aren't what they should be

  • Hi guys,

    I have a customer that's wanting to search a mailbox/online archive for multiple keywords (about 10). I'm noticing some strange results. Say the keywords are cat, dog, mouse, and cheetah. Using the OR operator and searching for cat OR dog OR cheetah will turn up less results than just searching for just cheetah or dog. It's almost as though it thinks I'm using AND instead of OR. Is there a limitation on how many keywords you can search for? As of right now my plan is to do separate searches for each keyword. The problem is that will lead to duplicate results, but since this for a legal matter I figure more is always better for less. Anybody ever run into this issue?
