      • By using {{query }}, the format is something like this:

      {{query Something you're looking for}}

;; Logseq's block order is determined by both :block/parent and :block/left.
;;
;; Let's say we have a list like this:
;; - 1
;;   - 1.1
;;   - 1.2
;; - 2
;;
;; Block `2`'s left is block 1, block `1.2`'s left is block `1.1`,
;; Block `1.2`'s left and parent is block `1`.
