Also, FYI, if you enable “Apply Hook Finder tags…” in Hook > Preferences > General, then a “Hook” Finder tag will be applied to each Hook-linked file when you link it/them (this does not operate retroactively. So you can use Spotlight to find them. (You can even create a .hook file that searches for all of them).
We intend to support random-access searching for other types of items besides files. We don’t intend to compete with search tools, but work with them. (The fact that Hook files can optionally be found with Spotlight is an example of that.) The philosophy of Hook is to be light-weight, to focus on its core “value add” (contextual information access), and to work well with existing tools.
one could in principle also find all files created via “Link to New”, and we will provide some support for that.
Hook also is compatible with HoudahSpot (you can link to searches and via its search results). HoudahSpot can also be used to find Hook-tagged files.
