From ff91d3a22b9a5ab9511f8ed8bffc895a991529f5 Mon Sep 17 00:00:00 2001 From: Alexander Korotkov Date: Thu, 13 May 2021 16:10:21 +0300 Subject: [PATCH] Improve documentation example for jsonpath like_regex operator Make sample like_regex match string values of the root object instead of the whole document. The corrected example seems to represent a more relevant use case. Backpatch to 12, when jsonpath was introduced.
