I don't know why it is so horrific with Shopify's unclear documentation. https://shopify.dev/concepts/about-apis/search-syntax#search-query-syntax, that specifically.
in admin/orders page attempting to query orders conditionally based on what has defined in the documentation referenced above.
What am I trying to achieve here?
Apparently my store has a Delivery Method namely "Scheduled Delivery" and timeslot tags specifically only to such orders. I would like to query my orders only for Scheduled Delivery without any tags
What I have tried?
1. I tried, and it show orders that didn't have anything tag to it. (which I also want to know why `tag` instead of `tags`, where are the listed fields that I can potentially query with?)
2. I would like to combine above queries conditionally to if only the order has a delivery method title of "Scheduled Delivery" and so I tried (which resulting zero);
"Scheduled Delivery" AND -tag:*
Do advise what I can do.
