 *Fields*:
 1. `kind`
    -  *Operators*:
-      -  `=${KIND_NUMBERS}` - delegatee may only sign events of listed kind(s) (comma-separated)

 2. `created_at`
    -  *Operators*:
-      -  `<${TIMESTAMP}` - delegatee may only sign events whose `created_at` is ***before*** the specified timestamp
-      -  `>${TIMESTAMP}` - delegatee may only sign events whose `created_at` is ***after*** the specified timestamp

-Multiple conditions can be used in a single query string, including on the same field. Conditions must be combined with `&`.
-
-Multiple conditions should be treated as `AND` requirements; all conditions must be true for the delegated event to be valid.
-
-Multiple comma-separated `kind` values should be interpreted as:
-```
-# kind=0,1,3000
-... AND (kind == 0 OR kind == 1 OR kind == 3000) AND ...
-```
+In order to create a single condition, you must use a supported field and operator. Multiple conditions can be used in a single query string, including on the same field. Conditions must be combined with `&`.
 
 For example, the following condition strings are valid:
-- `kind=1`
-- `created_at<1675721813`
+
 - `kind=1&created_at<1675721813`
-- `kind=0,1,3000&created_at>1675721813`
+- `kind=0&kind=1&created_at>1675721813`
 - `kind=1&created_at>1674777689&created_at<1675721813`
 
-However, specifying multiple _separate_ `kind` conditions is impossible to satisfy:
-- `kind=1&kind=5`
-
-There is no way for an event to satisfy the `AND` requirement of being both `kind`s simultaneously.
-
 For the vast majority of use-cases, it is advisable that query strings should include a `created_at` ***after*** condition reflecting the current time, to prevent the delegatee from publishing historic notes on the delegator's behalf.
