I have a site built using Sitecore 7.5 and Solr 4.7. I am noticing a very strange phenomenon where certain content items are not getting indexed. Here is what is happening.
I have a data template called "Content Page". Most of the content items that are using this data template live in /sitecore/content/Home/Corporate. Things like this:
/sitecore/content/Home/Corporate/About-Us
/sitecore/content/Home/Corporate/Careers
/sitecore/content/Home/Corporate/Terms-Of-Use
There are a few test items that I created that live in /sitecore/content like this:
/sitecore/content/Test-1
/sitecore/content/Test-2
All of these pages are built using the "Content Page" data template. After I rebuild the index and then go to the Solr UI and do a query I can't find any of the items that live beneath the Home node. When I do a query for _templatename:"Content Page" - I only get Test-1 and Test-2 in the results. Does anyone know why this would be happening? It's really odd. I've never seen something where Solr just doesn't index certain items at all. And it seems to be based on where they are in the content tree.
