The search page is the heart of Graylog usage. You can execute a search (query) and visualize the result with a variety of widgets. Enter your search queries in the field next to the green button with a white magnifying glass icon.
Any search can be saved or exported as a dashboard. Saved searches allow to easily reuse specific search configurations. Dashboards enable widget specific search queries and can be shared, so other people can use them in their processes.
For a better workflow, parameters can be added in the search query. Parameters are part of the Graylog Operations plugin.
