 There are some special cases:
 - If we want to use `LIKE` filter and query values that include a percent sign, it needs to be URL encoded (%25).
-- Dates must be in ISO-8601 format, `+` sign must be URL encoded (%2B). Single quotes for value are required.
+- Dates and instants must be in ISO-8601 format, `+` sign must be URL encoded (%2B). Single quotes for value are required.
 ```
