The PeopleAPI reference says how many is the maximum number of people.searchContacts?
There is a parameter in people.searchContacts that specifies the PageSize, and the possible range for this is 0-100 (if this is exceeded, the API will return an error with code 400).
In fact, the maximum number of contacts returned in my environment is 10.
When I call the API, I am doing so from the PeopleAPI reference. I have contacts with only names from "test001" to "test692".
I made the following call.
pageSize=100
query=test
readMask=names
In fact, the search is successful because 10 results are returned. The actual API response is as follows. Obviously, the object PERSON is only 10.

It seems to be a bug.
I have taken the liberty of filing it for you on Google Issue Tracker.
I recommend you to "star" it to increase visibility.
