FuzzyIdeas/Cling v3.3.0 on GitHub

Features

Exact mode: search literally instead of fuzzy matching, skipping app contents and system files. You can switch to it in Settings > Search, or toggle it with ⌘⇧X

Content search: search inside files by placing text in square brackets, like invoice [client] or .jpg [dog]

Needs Cling Pro

Date filters: dm: and dc: can filter by date modified or created like invoice dm:2025 or .pdf dc:7days

Operators from Everything, the Windows search app: content:, ext:, size:, file: and folder:

Action Bar editor: click an action to hide or show it, ⌘ Command click to move it between the bar and the ⋯ menu

Cloud filter: search iCloud Drive, Dropbox, Google Drive and OneDrive together, with ⌥O

Extension filters like .pdf and ext: no longer miss files in the Everything index after Cling restarts
Fixed a possible crash on quit while Cling saved drive indexes
Fixed a possible freeze during the hourly index check
Fixed a possible freeze after tens of thousands of files changed

Moving through the window's results with the arrow keys is smoother
A search that runs long turns its spinner red, and clicking the spinner stops it

⌃N and ⌃P can move through the results like ↓ and ↑. You can turn it on in Settings > Keyboard Shortcuts, which moves sorting by name and path to ⌃⌥N and ⌃⌥P

Files inside apps stay out of the index, except the app binaries, so Xcode's SDK headers no longer flood the results
in: takes a folder in Home without ~/, like in:downloads or in:documents/pdfs. With a drive filter or a one-folder filter on, it starts from that folder instead, like in:DCIM
Folders and Show in Finder use the file manager set as default (credits to @oenderg)
The search window works without Full Disk Access, like the search bar
The search bar's text stays readable over a dark window in light mode, and a white one in dark mode
