Extend searchWord rule to allow percent-encoded octets. Add comment that this actually is limited to Unicode letters and numbers:

; searchWord is a sequence of one or more letters, digits, commas, or dots
; this includes Unicode characters from the Unicode categories L or N using UTF-8 and percent-encoding
; the words AND, OR, and NOT are not a valid searchWord
; expressing this in ABNF is somewhat clumsy, so the following rule is overly generous
searchWord = 1*( ALPHA / DIGIT / COMMA / "." / "%" HEXDIG HEXDIG )

Description

The searchWord rule is overly restrictive as it only allows ALPHA and DIGIT whereas the comment states that any Unicode letter or number is allowed.

In other places where the ABNF does not exactly describe the syntax, it allows a superset that is then further restricted by the prose specification.
