Fixed in the next build. This occurred due to changes related to dynamic property deprecation in PHP 8.2. By defining a property related to the search index in a certain way, the code determined the property didn't need to be built, resulting in an empty search index.
In
src/addons/vw/vw/Handler/Search/Data/Base.php, find:
Code:
protected $validMetaData = [];
Replace with:
Code:
protected $validMetaData = null;
After making this change, go to AdminCP > Tools > Data maintenance > Rebuild caches > Rebuild search index.
You will need to run both "Wiki comments" and "Wiki pages".
I recommend setting the batch size to a low number like 10 since you have had server load issues in the past.
This corrected the issue on my test board.
