This index creator is used to always store a constant value decided at construction time. I know it is strange, but it is only used in a strange situation. Specifically, sometimes we want to _disable_ the forward index in a column with a text index in order to only let the user to search using the text index. There is a plan to actually be able to disable the forward index in that situation, but right now it is not possible, so the thing we do is to create a fake forward index that always store the same value for all rows. -- This is an automated message from the Apache Git Service.
