The crawler account has FullRead permission for the whole (the only) web application.
I have a content source set up for all the sites and site collections under the root URL of the web application https://....com:
Now when I use either search center page or CSOM with query text "WebTemplate:STS" the results don't contain the site collection under the managed path: https://...com/manpath/00000001
But when I explicitly set query text as "WebTemplate:STS AND Path:https://...com/manpath/*" I get the only result: my site collection under the managed path.
Is this an expected behaviour?
