Make any field searchable through basic sidebar search
|Knowledge Article Number||000004299|
The basic sidebar search is limited and typically only searches objects by the standard name field. If you'd like to enhance the sidebar search, create External ID fields since the sidebar search can search on External ID fields.
For example, if you have a custom object that uses an auto-number record format, you'll want to allow your users to search on another field so they don't have to search by record number. Another example could be if you wanted to have all of the Opportunities related to an Account Name show up by a basic search.
NOTE: If the object doesn't have a tab it won't be searchable. The tab visibility needs to be either "Default On" or "Default Off," it can't be "Hidden." If you don't want users to readily find this tab, set the visibility to "Default Off" and don't add it to any applications.
