Partial term matches in Studio

If a term contains a shorter term then the shorter term may or may not be recognized. It seems that there is a switch that controls the term recognition whether to display only the longest one or all the included terms.   Examples: a phrase contains a word: "request for asylum",  "asylum",  or also happens if a word contains another shorter word like:  "matter", "mat".    It works in one way in one machine and and another way on another machine. Can you tell us how can we change this settings? We cannot find it.
