Detailed Description

Create keyword expression that memoize the provided string pattern.

Each rule string is defined by:

<rule> ::= <operator><scope> " " <pattern> | <operator> " " <pattern> <operator> ::= "+" | "-" <scope> ::= "v" | "e" | "c" <pattern> ::= <ascii-text> | <wildcard> | <pattern> <ascii-text> ::= [#x20 - #x7e] <wildcard> ::= "*" | "?" | "[" <ascii-text> "]"
