Searching by Categories (using Search Portlet or Blog Portlet Search) seems to be case sensitive.
1. Created vocabulary called Fruit
2. Created the following categories and sub categories
3. Created Blog Entry 1 and used category Red
4. Created Blog Entry 2 and used category Green
5. Searching for Red or Green in Blog Search returns the correct Blog entry.
6. Searching for red or green in Blog Search returns nothing
7. Searching for Red or Green in Search portlet returns the correct Blog entry.
8. Searching for red or green in Search portlet returns nothing.
Is this by design? I would have expected the search to work using either upper case or lower case for the category name.
