# Description
This PR aims to address the following issues:
* Fixed problems where prefixes and suffixes in the Lorebook prompt were
affecting keyword matching logic.
1. In full word matching, the first and last words of the body text
would consistently fail to match.
2. In general matching, using a persona name as a keyword would always
result in a match, regardless of context.
* I tried to preserve the original code structure as much as possible
while implementing these fixes. Please feel free to suggest changes to
the approach if you see a better way.
Thank you for your time and review.
