question

The colon can be escaped with a backslash. Some of these characters can be 'escaped' by replacing them with an escaped whitespace. Multiple special characters sometimes may get condensed. I tried a few times and could match "foo$%^bar" by filtering for "foo\ bar". The behaviour is not always predictable. You might be better off filtering manually.

Wow, this is reaaaally bad. Hey, Amazon team, any plans on fixing that or providing documentation how to escape 'filters' param?

Hi there, It looks like our API documentation doesn't list what to do with escaping characters in filters. We will ensure that these are added as soon as possible. However, the following should describe what to do with escaping characters: CDS Supports escaping special characters that are part of the query syntax. The current list special characters are: + - && || ! ( ) { } [ ] ^ " ~ * ? : \ To escape these character use the \ before the character. Hope this helps! Jamie
