To add any selection as a rule, you need to
highlight the selected text
right click and select LevelOps > Add selection to LevelOps Rule
If you want your selection to work as a simple string match, just click on "Escape special characters" in the pop-up.
This will ensure that the selected string will be match-ready
When you want to add stack traces or multi line matches as a triage rule, you need to ensure that you are not including any line numbers or log time stamps in your rule. Lets look at the lines below
When I want to create a rule, I do not want to include "Jul 08, 2020". So we will delete any time stamps from the selection
Now just append [\s\S]+ between the lines
Now, this is ready to run as a rule match for the stack trace
