This is similar to This Feature Request, so you might want to vote for that and/or add some commentary that would augment the requirements already described there.
If this resolves your issue, please mark this post as the solution.
Just to be sure I’m not missing something obvious…
You are on an Enterprise or Pro license
You have added an Execution Data node somewhere in your workflow to save a data value (any value from anywhere in the workflow, including a query parameter passed in on a webhook) in a Highlighted Data Tag.
Note: Last one wins, so if you have multiple data items, whatever the last one assigns overwrites the rest for any given tag name.
You put the same tag name in the execution filters to find executions matching the value you are seeking.
Initially, I thought you were looking for something else, but when I re-read, I started to think maybe you were just looking for step 2.
If this resolves the issue, please mark this post as the Solution.
The reason you are probably not seeing the feature you want (searching for a specific execution by the data it processed) is that the feature is only available with an enterprise license (if self hosted), or the pro subscription (if cloud).
If you wanted to create your own alternative, you could add a step to the workflow which stores a record/document in an external database (airtable, mongodb, etc), containing a url-link directly to the execution data, using an expression like http://myn8n.example.com/workflow/{{ $workflow.id }}/executions/{{ $execution.id }}, and correlate anything else you need to search by (input-param value, rep-id, account, timestamp, error code/message, etc.).
If your question has been answered, don’t forget to mark the post with the best answer as the solution.
