+_<abbr title="Too long; didn't read">TL;DR</abbr>: For best results, use the [default combinators and operators](./misc#defaults) or map custom combinators/operators to the defaults with [`transformQuery`](./misc#transformquery)._
+
+While `formatQuery` technically accepts query objects of type `RuleGroupTypeAny` (i.e. `RuleGroupType` or `RuleGroupTypeIC`), it is not guaranteed to process a query correctly unless the query also conforms to the type `DefaultRuleGroupTypeAny` (i.e. `DefaultRuleGroupType` or `DefaultRuleGroupTypeIC`).
+
+In practice, this means that all `combinator` and `operator` properties in the query must match the `name` of an element in [`defaultCombinators` or `defaultOperators`](./misc#defaults), respectively. If you implement custom combinator/operator names, you can use the [`transformQuery` function](./misc#transformquery) to map your query properties to the defaults.
+
+For example, assume your implementation replaces the default "between" operator (`{ name: "between", label: "between" }`) with `{ name: "b/w", label: "b/w" }`. Any rules using this operator would have `operator: "b/w"` instead of `operator: "between"`. So if a query looked like this...
+
+```json
+{
+  "combinator": "and",
+  "rules": [
+    {
+      "field": "someNumber",
+      "operator": "b/w",
+      "value": "12,14"
+    }
+  ]
+}
+```
+
+...you could run it through `transformQuery` with the `operatorMap` option:
+
+```ts
+const newQuery = transformQuery(query, { operatorMap: { 'b/w': 'between' } });
+// {
+//   "combinator": "and",
+//   "rules": [
+//     {
+//       "field": "someNumber",
+//       "operator": "between",
+//       "value": "12,14"
+//     }
+//   ]
+// }
+```
+
+The `newQuery` object would be ready for processing by `formatQuery`, including its special handling of the "between" operator.

 The `query` prop follows the same format as the parameter passed to the [`onQueryChange`](#onquerychange) callback since they are meant to be used together to control the component. See [examples](https://github.com/react-querybuilder/react-querybuilder/blob/main/examples).

 Pass `true` to automatically add a rule to new groups. If a `query` prop is not passed in, a rule will be added to the root group when the component is mounted. If a `query` prop is passed in with an empty `rules` array, no rule will be added automatically.

+Pass `true` to update rule values that represent lists with proper arrays instead of comma-separated strings. Applies when `valueEditorType` is "multiselect" and when a rule's `operator` is "between", "notBetween", "in", or "notIn".
+
+For example, the default behavior for the "between" operator might produce this rule:
+
+```json {4}

+  "value": "f2,f3",

-Pass `true` to insert an independent combinator selector between each rule/group in a rule group. The combinator selector at the group level will not be available. Visually, this is similar to the [`showCombinatorsBetweenRules`](#showcombinatorsbetweenrules) option, except that each combinator selector is independently controlled. You may find that users take to this configuration more easily, as it can allow them to express queries more like they would in natural language.
