It seems that Hebrew is not one of the built-in supported languages and it doesn't seem like there is a way to add custom dictionaries in Aurora Serverless Postgresql.
Is there a way to get full text searching to work with Hebrew, and if so, how?
I thought that there might be a way to set up a custom dictionary using the .affix and .dict files that are available as part of Open Office (and other products/services).
However, even once I found the files, I didn't see a way to make them available to this version of Postgres. On the other hand, it's hard to imagine that Amazon wouldn't provide a way to do full text searches in any language.
