When two results look almost the same, such as two log lines from the same service, comparing their field values side by side shows exactly which values differ.
Open Discover and run a query that returns at least two results.
In the results table (the Results tab, or Documents in classic mode), select the checkbox of each result you want to compare. Select at least two. You can compare up to 100 results at a time.
From the Selected menu in the table toolbar, select Compare selected. The comparison view opens and shows the selected results next to each other.
Compare the values of each field. By default, the first result you selected is the reference for the other results. A value that matches the reference is highlighted in green, and a value that differs is highlighted in red.
To use a different result as the reference, open the contextual menu of that result and select Pin for comparison.
Optional: To change how differences show, open Comparison settings. You can turn off difference highlighting, show differences by line, word, or character, or turn off Show matching fields to hide fields whose value matches in every result.
To leave the comparison view, select Exit comparison mode.
Result: The comparison view shows the selected results next to each other, with the differences highlighted.
To read every field of a single result, refer to Inspect documents and requests in Discover.
