Hi thanks for the lib! I see the `{{state.isTriggered}}` is a boolean. However, I cannot write down that format:

If I use "{{state.isTriggered}}", then the document fail to index, because boolean fields cannot accept string values.

In addition, for values with type `date`, it seems that, when it is empty, the `""` will fail to index?

Thanks!

This seems like a bug to me. Can you post it here?
