Handle reserved word case-sensitivity

[snowboardit]

For context, we are simply checking word(s) arguments with language words directly. Currently, there is no case conversion happening.

To better inform the user, we should output if any word argument(s) matches closely, in addition to exact matches.

For example
We query for the word set in both lower and uppercase and find completely different results
