Feature Description

Currently, keyword filters seem to work as wildcards and allow partial matches. Whitespace either side also seems to be ignored. This means that a filter for "EP" would also filter "Epidemic" or "Step".

Given that current users may want to filter short terms like "AI", it would be nice to either be able include whitespace (i.e " EP "), provide regex (i.e "\bAI\b"), or mark a keyword as requiring the whole word in order for a filter to activate.
