In Confluence, when the user clicks on the magnifying glass in the sidebar, it will open the Quick Search field and it will allow the same to search for multiple contents like pages, attachments and configuration options.

However, in those parameters, the labels are not included and this could be really useful to work with quick results and not consume time by going to the search page and configure the label parameters. This is a suggestion to make the labels searchable in the quick search of Confluence.

Workaround

Use the full search of Confluence. Under the Add Filter part, make sure to select Labels.
