Searching with "%" seems not to work as you expect. I only do get meaningful results using "*".
But you are 100% correct: Tags can not be searching using the 'condition'-API request.
Once again it was a pain to find this out (due to your reply) - this should be clearly stated by the documentation (which IMHO is a pain too - at least the one onloine on https://kb.i-doit.com/ ).
As a workaround I will use the old idot.search. This one is able to find tags.
The results must be filtered for the key * > Tags.
But that's much faster as other things I tried.
Thanks and have a good day,
Wolfgang
