How can I match summary of 1 sub task with other sub tasks using Automation

[Peyush Agarwal]

Hi,

Problem is I have a task where users can create Sub task for operational issues. Many times, similar sub task is created so essentially it results in Duplicate task. 

I want to put a automation in place such that Summary / Description can be matched and user can recieve an email for that. 

e.g. 

JIRA-123 is Main task 

It has 

JIRA-234 - Summary "Automation not working"

JIRA-235 - Summary "Something wrong with Automation"

JIRA-236 -  - Summary "Manual has issues"

User creates a JIRA-237 and automation is triggered to check if summary matches of 237 with 234/235/236

if 237 has Summary as "Automation needs to be fixed", user can get an email that as per Summary mentioned, JIRA-234 and JIRA-235 look like something similar. Can you please review those
