There is a root web application
And it hosts 2 host-named site collections
"webapp" is the Content Source. The crawl log show "sites" has numerous "Successes" and "teams" has 0 activity.
This is a rebuilt Search Service Application configured identical to the predecessor and have NOT had this issue previously (rebuilt due to index corruption).
- search permissions are full read on the web app
- checked for crawl rules that would exclude crawling (I also attempted a rule to force/include the missing site collection using the permissions of the farm admin account)
- root site collection exists (crawl worked fine using a previous instance of SSA)
- the default zone web app url is the content source and the index was reset (also new index)
What else should I investigate?
