I think I don't understand what you want to do...
>>> probe parse "thisisaverylongstringwhichcouldbeusedbyparse" "very"

>>> parse/all "thisisaverylongstringwhichcouldbeusedbyparse" {"very"}

Used this way, PARSE splits your string based on the delimiters
you give as the second argument.
>>> probe parse "thisisaverylongstringwhichcouldbeusedbyparse" [ thru "isa"
R> to "long" ]
R> == false
Here, PARSE applies the rule given as its second argument to the
string. The rule does not reach the end of the string, so PARSE
returns false.
Maybe you just wanted this?
>> find "thisisaverylongstringwhichcouldbeusedbyparse" "very"
== "verylongstringwhichcouldbeusedbyparse"
Regards,
Gabriele.
