I just got a new computer here at work, and this was one of the new features it has. I have just started using it, and I am still getting used to the way everything works. I find it interesting what new things are showing up in my search results that I did not find before, however this can be a double-edged sword, as I will explain better below.
I dislike having to learn, or re-learn as the case my be, where everything is located or set up. I prefer when things work the way I am used to, for expediency sake. Also, (and here's the opposite edge of the aforementioned double-edged sword), sometimes the search can throw some weird and completely unrelated things into your results, which means I have more to wade through before I find what I am actually looking for.
Still too new to make any recommendations of any worth. I prefer to leave reviews of some worth.
When performing a search, I now have more options that show up in my results. I don't know if that is solving anything just yet, as I am still a brand new user. However, while it takes me more time (sometimes) to find what I have actually been looking for, there have been a couple of times that I found unexpected and useful results. I am still learning the capabilities of this program.
