Filter value formatting might fail on custom Search API field types

Automatically closed - issue fixed for 2 weeks with no activity.

Hello I am facing an issue with the addition of this commit when using custom Filter on date_range fields.

Steps to reproduce:
1. Set the "date range from" value to a specific date, e.g., "2024-03-04T00:00:00Z".
2. Set the "date range to" value as "*"(indicating a undefined range). - the formatFilterValue function returns 0 instead of the value itself.
I believe this case needs to be treated.

Thank you!
