I have been meaning to ask this for some time.
I always try to get the tags in such a way so that posts that are related appear in the "related posts" bit. However I have noticed that older posts' recommendations are not changed over time. For example if I did a post
"5 ways to improve X" in October
and later I posted
"6 more ways to improve X" in November
in the second one I would be told there is a post called "5 ways to improve X", while the first one would not tell me there is a post called "6 more ways to improve X".
Have I managed to explain myself?
In other words YARPP only seem to be looking at the post at the moment of publication, and it never re-examines the situation to make sure everything is up-to-date. Is there a way to make it refresh the content it produces at least now and again?
