Hi Nancie,
thank you for reaching out! I'm the product manager of Service Desk, recently joined the team here at LogMeIn.
Regarding the feedback sharing portal: for now, it's perfect (and I appreciate it) if you share any feedback or ideas here at the Community portal. We might intrdouce a more targeted portal for this in the future, but we'll let you know if that goes live.
Regarding Search: unfortunately the search capabilities you asked about are not available today. We realized that Search in Service Desk needs major improvements to be effective and to make you more productive hence it is on our radar. We are working on the roadmap of Service Desk, Search improvements is certainly an item on it and your feedback is a great input for that. I will share with you the planned product changes and the roadmap in the near future.
Thanks again for the feedback,
Mark
