I have been finding the Tag feature increasingly helpful. All of my hundreds of thousands of digital images taken over a period of 25 years are archived by means of a unique code (which I use as the filename). I’ve started putting this image code in the Tags of my observations. That makes it really straightforward: if I want to check the ID of a species in one of my photos, I can simply search for the filename; conversely, if I need to find the original image file corresponding to an observation, the filename(s) are right there. Really useful!
I haven’t been able to locate any documentation about Tag functionality. Is there any such information? There’s a few things that I am wondering if it is possible to do:
Firstly, is there a straightforward way (other than downloading all my data as a spreadsheet) to search for all of my observations that don’t yet have any Tags?
Secondly, is there any straightforward way to search a partial match on Tags? All my image codes start with a prefix denoting which camera I used. It would be neat if I could limit a search for all observations that have a Tag starting with “S”, for instance – effectively allowing me to filter my observations by camera (which would be useful as I have different types of cameras; camera “T” is an automatic camera trap for example, while “S” is a DSLR and “E” is a smartphone).
Thirdly, it seems that all my Tags are visible to everyone. But these Tags are for “internal use only”, as it were, i.e. they are meaningful to myself only. It seems a lot of people use Tags in such a way, so is there a way to turn off public visibility of one’s Tags?
