@romungi-MSFT thanks for your answer

For my case，i have to set offset > 0 and count > 0 to get the relatedSearches object in the response. If i don't use any other filter params or set offset = 0, then i will not get the relatedSearches object. Anyway, the problem solved --- in some weird ways :-) .
