I am trying to create a feed of posts that have both #blacksky and #photography tags. Creating a single Entity List block with "in list: hashtags: blacksky, photography" does not work, this lists posts with #blacksky OR #photography. Creating two Entity List blocks — one with "in list: hashtags: blacksky", the other "in list: hashtags: photography" causes the scanner to pinwheel forever (over 700k posts in the preview tool with no results). So a few suggested resolutions here… The feed should correctly recognize multiple "Entity List: In list: hasthags" blocks. The first dropdown should have the options "any in list" (replaces "in list" as an OR filter) and "all in list" (a new AND filter) 2a. If this resolution is pursued, the UI should either prevent multiple "Entity List: In list: hashtags" from being placed, or raise some kind of error. Note that a combination of "Entity List: in list: hastags:" and "Entity List: not in list: hashtags" filters does work fine, so the issue seems to be the actual filter trying to handle contradictory instructions.
