Sort By Keyword But Only One Folder

[STLnikon]

New to this community. I have a big collection Windows folders, each folder holding a group of photos, in Lightroom Clasic. All photos of my son have "Mike" as a keyword. When I has a specific folder open and request all photos with keyword "Mike", I get ALL of the photos from all the folders. How can I limit the search to the specific folder I am viewing in LC? A more specific example: I have 500 photos of a baseball game in a folder. My son is only interested in photos of him at that game. Thanks.

I would think to use the Filter search above the Grid window. Press [\] key if not visible.

You can then search for 'Text / Keywords...'

Perfect!! Works!! Makes sense to open folder on Lightroom, use Grid View, then set up filter by keyword on top window. Not the keyword list on the right column.
