This solution was ultimately chosen by the users who appreciated the optional client search (it wasn't determined that this was a necessary data point) and the more specific search boxes. This is an example of how more isn't always better. The users reacted to this design very well and verbally praised the simplification saying "This is exactly how I use this tool. Thank you for making it easier and faster".
There was discussion among the team that perhaps the original adjusted search solution was better because it allowed access to more data at once and that that search format had served larger companies and applications. I pointed out that things that work, even for large and popular application, doesn't suit all user needs across the population of users using something like a search function.
The users expressed that they were excited to see what we brought to them in the following weeks and that they appreciated having a regular forum to discuss issues like this with the development team.
