This expression could not be parsed

The first step of interpreting a relevance statement is parsing the expression into its various

components. This error results from a failure of the parsing engine. This is typically

caused by unmatched parentheses or by syntax errors involving certain reserved words used by

the parsing engine. Reserved words are syntactical statements like of, and, equals, and so

on.

Here are a couple of examples:

Q: = )
E: This expression could not be parsed.
Q: Name of (file whose (version of it = "2.6") of system folder
E: This expression could not be parsed.

The expression:

Exists file "name" of or system folder

Will return the same error message due to the improper use of the reserved words of and or. This error is a catch-all for ungrammatical arrangements.
