GET /multiterm/api/1.0/termbases/search

I'm getting same result from search method, regardless of the FROM parameter value
e.g. termase has 1000 concepts, with ids from 1 to 1000 and I need to get concepts from 250 to 350
I filled pageSize to 100, and FROM value = 250, and i got concepts from 1 to 100
I've found same topic on the forum:
