Use exact match by default for inverse search term

Browse Source 
This is a breaking change, but I believe it makes much more sense. It is
almost impossible to predict which entries will be filtered out due to
a fuzzy inverse term. You can still perform inverse-fuzzy-match by
prepending `!'` to the term.

| Token    | Match type                 | Description                       |
| -------- | -------------------------- | --------------------------------- |
| `sbtrkt` | fuzzy-match                | Items that match `sbtrkt`         |
| `^music` | prefix-exact-match         | Items that start with `music`     |
| `.mp3$`  | suffix-exact-match         | Items that end with `.mp3`        |
| `'wild`  | exact-match (quoted)       | Items that include `wild`         |
| `!fire`  | inverse-exact-match        | Items that do not include `fire`  |
| `!.mp3$` | inverse-suffix-exact-match | Items that do not end with `.mp3` |
