+/**
+ * A hook that provides fuzzy filtering functionality for a list of objects.
+ * Uses match-sorter to perform the filtering across multiple object properties and
+ * consistently order the results by score.
+ *
+ * @param params - The parameters object
+ * @param params.items - Array of objects to filter
+ * @param params.keys - Array of object keys to perform the fuzzy search on
+ * @returns An object containing:
+ *   - filterText: The current filter text
+ *   - setFilterText: Function to update the filter text
+ *   - filteredItems: The filtered array of items based on the current filter text
+ *
+ * @example
+ * ```tsx
+ * const users = [{ name: "John", email: "john@example.com" }];
+ * const { filterText, setFilterText, filteredItems } = useFuzzyFilter({
+ *   items: users,
+ *   keys: ["name", "email"]
+ * });
+ * ```
