Jan 2 at 2:11 comment added Tallboy this is a great answer - is there an index you might recommend if I'm not doing a comparison with a threshhold? Im literally showing the actual similarity to the user as a %, so they know if some content they created exists with in the last 5 days. In this sense, i need to do a cross join similarity score on ALL x ALL from last 5 days. from what i gather no index well really help here.. but is there anything else that might speed this process up?

suggest pg_trgm.similarity_threshold instead of the deprecated set_limit(); reformat, denoise, links
