Thank you for your quick answer , if i disable the matching by Tags ( which is the only option i am enabling on all other criterias ) how the plugin is going to give related posts ? based on what ?
i already disabled matching by title and by content , and set sorting to random ,
i have a question about the mechanism your plugin search for related posts : does it read/search all 50.000 articles everytime it need to match the criteria or does is stop after finding the first 10 matches ??
