Is it possible to sort search results by a custom mask field, like a custom date?

Unfortunately I wasn't able to find anything clear on the topic online.

This is not possible by configuration only, but I would see two possible solutions for this requirement:

• Use a hook in the page indexer to set the sortdate in the index table to the desired value or fill that value in your custom indexer.
• Add a column in the index (like my_custom_date), set that date in the page indexer hook or in your custom indexer and add that column as custom sort field as described in https://docs.typo3.org/p/tpwd/ke_search/main/en-us/Configuration/Sorting.html#sorting-own-options
