Title: Using the Index Manager

Describe the issue:
"IndexManager" is a single technical term, so depending on the context it should be either "index manager" (no capital letters) or "Index Manager"

"The automatically mapped results return as lists of managed entities. " >> "The automatically mapped results are returned as a list of managed entities."

The wording difference is needed to highlight that they are returned from the API method, they don't "return" by own initiative.

#3 is not relevant. There is no Hibernate nor a persistence context. Just remove the point.
