  `findPath` is a utility function for finding the rule or group within the query hierarchy that has a given `path`. Useful in custom [`onAddRule`](./querybuilder#onaddrule) and [`onAddGroup`](./querybuilder#onaddgroup) functions.
  +### `convertQuery`
  +
  +```ts
  +function convertQuery(query: RuleGroupType): RuleGroupTypeIC;
  +// OR
  +function convertQuery(query: RuleGroupTypeIC): RuleGroupType;
  +```
  +
  +`convertQuery` toggles a query between the conventional `RuleGroupType` structure (with combinators at the group level) and the "independent combinators" structure (`RuleGroupTypeIC`, used with the [`independentCombinators` prop](./querybuilder#independentcombinators)).
  +
  +`convertToIC` and `convertFromIC` do the same thing as `convertQuery`, but only in one direction.
