Users MUST be able to search their own Licensed Image libraries. The filters panel has dozens of other options, but not the ability to onll look in a specified User directory.
This appears to be clearly articulated user need that has gone unaddressed by the Adobe Stock team for 2 - 3 years. Meanwhile, pexels, unSplash, rawpixel, nappy, and mutliple other sites make searching my own folders of images effortless.
Thank you for posting this feature request to be able to search within libraries or license history. You cannot currently search within license history, however you can search your libraries from within a Creative Cloud app.
Open the Libraries panel and you can switch back and forth between searching in Adobe Stock or Searching in Current Library or All Libraries:
I have forwarded your feature request to our product management team.
