fix(rpc): suggestions should only suggest based on <keyword>%

Previously, Python code was looking for suggestions based on
`%<keyword>%`. This was inconsistent with PHP's suggestion
implementation and cause more records to be bundled with a suggestion,
along with supplying misleading suggestions.

Closes #343
