Many options can do lots of stuff and that seems like enough words.

I really like the Hawk preview and ability to see why a search result set is populated as such.

Hawksearch provides functionality we need at a fair price, with tools developed both in mind of developers who will implement and business users that will administer them. They never stop in evolving their tools nor listening to customers to add to their roadmap. Working with them is a positive experience and one in which I feel like we have a true partner as oppose to just another technology vendor.
