 * I’m getting a range of database errors shown in Query Monitor when using Relevanssi
   and no results are returned.
 * Would this be something related to Relevanssi or our theme/server?

 * You have `WHERE post_parent IN ()` in there, ie. you’re looking for an empty `
   post_parent` value. That’s breaking the MySQL query and causing Relevanssi to
   find no results.
 * You have some kind of `post_parent` restriction in the search, and it’s failing.
   How is it set up?

 * Hi Mikko, sorry for the late reply. I’m not 100% sure what you’re asking, would
   this be something dictated by our Theme and how it has set up the search? Or 
   a possible plugin conflict?

 * It may be a theme or some other plugin; something is adding a post parent restriction
   to the search, and that’s failing there. I can only tell what’s happening, I 
   can’t tell why.
