-For now, the MongoDB export format has two major shortcomings. For one, it does not support the inversion operator (setting `not: true` for a rule group), however rules _can_ be created using the `"!="` operator. Also, if the query uses [independent combinators](./querybuilder#independentcombinators), it will not be processed and `formatQuery(query, 'mongodb')` will always return the [fallback expression](#fallback-expression).

+### Spring Expression Language
+
+For Spring Expression Language (SpEL) output, use the "spel" format.
+
+```ts
+formatQuery(query, 'spel');

+Output:

+### JsonLogic
+
+The "jsonlogic" format produces an object that can be processed by the `jsonLogic.apply` function (see https://jsonlogic.com/).

+```ts
+formatQuery(query, 'jsonlogic');

+Output:

 ## Configuration
 
 An object can be passed as the second argument instead of a string to have more fine-grained control over the output.

 ### Fallback expression
 
-The `fallbackExpression` is a string that will be part of the output when `formatQuery` can't quite figure out what to do for a particular rule or group. The intent is to maintain valid syntax while (hopefully) not detrimentally affecting the query criteria.

-By default, `fallbackExpression` is `"(1 = 1)"` for the "sql", "parameterized", and "parameterized_named" formats, `"1 == 1"` for the "cel" format, and `"{$and:[{$expr:true}]}"` for the "mongodb" format.
