is strange if that support nip-91 "AND operator for filters", but not this.

However it always seems to look for lowercase in the example

Applesauce explicitly transforms all hashtags to lowercase when creating or parsing events content. I cant find the nip anymore 😢 that defined that hashtags MUST always be lowercase but its needed for the "t" tag to work correctly with dump relays

that or relays need to transform all "t" tags to lowercase when indexing 😞
