Search a folder, display found items and enable open by clicking

First time poster and short-term user of KM (but loving it)!

Would appreciate some help in figuring out how to set up a macro to do the following:

  • have a pop up window in which to input a word and / or words for searching
  • search an already defined specific folder (and sub-folders in stated folder) for these words and / or words
  • have another pop-up window to display said results of search for opening via double clicking

Would be great if the search results stay open until they are dismissed / cancelled.

Don't know if that's possible and apologies in advance if already covered somewhere else (did check but not found) - looking forward to hearing from you and thanks in advance for your time.
