i am working on sharepoint server 2013. and i want to define a new Result Source. so i went to "Central administration" >> "Managed Services" >> "Search service" >> "Result Sources". then i created a new Result source, and i open the Query builder. now inside the query builder i find a managed property named "Wiki Category" as follow:-
but i am a bit confused on which site collection this WikiCategory belongs to ? as in my case i have one web application and this web application contain 6 site collections, and 2 site collections are of type Enterprise Wiki. so how i can know the site collection the WikiCategory belongs to? as i have multiple site collections, and i am defining the Query at the Search Service level, which is on top of all the site collections?? or this WikiCategory will refer to multiple site collections ?
