I have a memory of reading around these parts that a #hashtag with #underscore is considered the same as without. But one does not bring the other via search in #webUI ...
with (#X_Y_Z): https://mastodon.social/@parvXm/109574217441504027
without (#XYZ): https://mastodon.social/@parvXm/109574218679298171
... what am I missing?
