You need to think about how a predicate would work against a SQL store. The
left-hand side of the expression cannot be anything other than the name of a
column or a path to the name of a column.
Have you thought of using either "path LIKE ..." with wildcards, or "path
MATCHES ..." with a regex expression?

is the page that discusses these ideas, look for the String Comparisons
section.
