---------------------------------------

I know, that's why I'm referring to it: since you fixed that, I'm assuming you're aware of the kind of special considerations we need to apply in this area: we can't allow users to play with random flags as there are various complexities which need to be taken care of.

> QueryInterceptor uses the return value from RemoveCommand/ReplaceCommand to remove the value from the index.
> But both RemoveCommand and ReplaceCommand have a variant with an expected value parameter, and this variant return a boolean value instead of the removed/replaced value. In that case, the previous value won't be removed from the index.
> QueryInterceptor should probably use the previous value from the context entries to update the index instead.
