Describe the issue you are experiencing
The problem
The Automation Dashboard search fails to find an automation when searching for the last word of its name, ONLY if the name starts with _0 (underscore zero). Unclear exaclty the logic _00 / _001
The combination of a leading _0 and searching for the final string token causes the search filter to fail. Some other combo at the front probably too.
Automations Dashboard (Frontend)
Describe the behavior you expected
Any search token (word) in the search Automation should return all automations sharing this token (word).
Caused a major issue where I never found this critical (Heating) automation I needed to adjust. It's -15C (Montreal, Canada) which led me to research this bug.
Steps to reproduce the issue
I isolated the issue with the following tests:
Test 1 (The Bug)
- Name:
_001 SOL Timed 0845 Prep Day Set Heat - Search Query: "Heat" (The last word)
- Result: ❌ No results found.
Test 2 (Control - No Prefix)
- Name:
SOL Timed 0845 Prep Day Set Heat(Removed_001) - Search Query: "Heat"
- Result: ✅ Automation found.
Test 3 (The Bug - Different Word)
- Name:
_001 SOL Timed 0845 Prep Heat Set Day(Changed last word) - Search Query: "Day"
- Result: ❌ No results found.
Test 4 (Control - No Prefix)
- Name:
Timed 0845 Prep Heat Set Day - Search Query: "Day"
- Result: ✅ Automation found.
