The default criteria for the index search page is to search against all logs collected by the appliance (except the appliance’s own logs) and for the last hour. You can search using these defaults or change them.
Procedure
Access the Index Search page from
Search > Index Search.
Enter your search expression in the search text box and click the
Run button.
Note: Do not use < or > in your search expression, as these are not valid characters.
If you want, you can adjust the search scope and rerun the search by selecting specific log sources and/or a different timeframe.
