Hi all, This is not intended behavior, it is a bug. I will check in a fix soon ...

"baby to" , "baby too" match C1305907 of "baby tooth", however "baby token" does not match it. "electrolyte le", "electrolyte lev" match C0428284 "electrolyte level", but "electrolyte dev" does not match. It seems if the "missed" word contains the same characters that the word found in the fast dictionary starts with, a match is made? Is there any way to tweak or customize this behavior?

The lookup allows for a certain number of "misses". The "baby to" hits on "baby" as the rare word. "baby to" compared to "baby tooth" is 1 "miss" and qualifies as a match. (in practice, if I recall correctly, "to" is actually discarded entirely, so the comparison is actually "baby" : "baby tooth"). Others can correct my napkin logic though. This is a pretty common scenario when a single term ends up matching to a larger term because of the allowance of misses. For example: "oxygen" > "oxygen therapy" "pathology" > "pathology department" , "pathology procedure" "exercise" > "exercise pain management" Those are just some quick examples. It depends heavily on what the ontology contains though.
