Not sure if there is a Splunk standard, but it does make it nice to come up with a standard naming convention to organize your searches.
For example I begin some of my search names with audit (ex: audit_fails, audit_successful). Then under my app I go into manager - user interface - navigation menus - default and added the following under
So any time I create a search with the word audit it automaticly gets placed in the searches menu . I have another for my Database searches that I start with db_ (ex db_group1, db_group2) so it can get organized in a menu just for them so I am not scrolling through my other search to find them.
