I have several items (news stories) that are contained within a section (like a category) that span multiple issues and publications. The sections are mostly repeated in every issue and many times the sections are in the other publications as well. What I want search to return is a list of all items that are contained within the same section regardless of publication or issue.
I think the correct answer is to add the section identifier field value from the section item into the index on the story item document that I'm searching against. But I'm having trouble finding a good source on how to do that using Sitecore 8. More specifically I'm using Azure Search, but that only changes a few things that I think I've been able to figure out.
For simplicity I'm just using the default sitecore_master_index for now at least. I'll probably create my own index specifically for this and other purposes.
