Just downloaded and tried your plugin. Looks amazing but.. :)
Short intro: I'm very dull person and have tagged all my posts. These are basically keywords, describing my content.
So, I do not rely on full text or title relevance in plugin, but put main stress on tags.
At the moment I'm trying to tweak pluging to show posts that are really related and try to avoid noise.
What I mean by "noise"? Assume I have renewable energy blog. All posts are manually tagged and between them there is semantic link.
Main article: Solar and Wind Industry in Pakistan
Tags: Wind, Solar, Pakistan
Related list & Tags:
Jamaica hybrid system : Wind, Solar, Jamaica, islands
Russian energy: Wind, Solar, Russia
European spendings: Wind, Solar, Europe
Ukraine investments: Wind, Solar, Ukraine,
Wind Farm in Pakistan: Wind, Pakistan
In my opinion, the most relevant here is "Wind Farm in Pakistan", because terms "Wind" and "Solar" are so frequent, that they does not give any information for sorting, therefore represent simple "noise" here.
So, my question is - can I tweak settings somehow to show "Pakistan" on 1st position and in future - show Pakistan-related articles first?
