I like all three ways you could search using your own keywords as well as synonym matching (such is my preferred method). It was very hard at first figuring out how this new program compared/relates back tot he old one but now i understand why they had such big changes when switching servers over from seeunity 6 -8 years ago so its not just because people didnt know what we were doing before! Make sure u read up about where ur looking through discovery center or else find someone who knows their stuff better than me lol otherwise everything will click into place after searching around awhile!! We've used many versions previously including 3rd party products which has been difficult managing files between clients if different users are involved also in previous version there would sometimes be issues relating dates being entered incorrectly etc.. I like how easy they made everything very simple for me so i could get my work done efficiently. Nothing really but if you are looking something different from what others do this is great! It has helped me greatly when doing some research online or even at school just having them search as well. They aren't open source which would be better because then more people will use their product instead of paying money each month for subscription fees.
