Drupal 9: Using Taxonomy Terms To Create A Related Content Views Block
For the last few years I have been tagging articles as I write them on this site. This tagging has largely been to tie posts together in an aggregated list of other posts tagged with that term. I recently wondered if I could use those tags to show related content below each article. I have struggled with this feature on client websites in the past and it either boils down to a manually curated list or some sort of complex content analysis and Solr search.
As it happens this is fairly easy to accomplish using Views, although took some working out to get the effect I wanted. I'm writing down these instructions to help me remember how I did it in the past and to allow you set up the same thing (if you wish).
