If you can't find a Record you're looking for:
First, review the full set of Records you can search for with Dropbox Dash
If you are searching for a Record from a supported Service, check that you've connected it in the Dropbox Dash desktop app's Settings:
For cloud apps and services visit Settings > Integrations
For local files and folders, visit Settings > Search Directories
Note that if you have the Dropbox Dash browser extension installed, web pages you've previously visited may be available in the Dropbox Dash desktop app even if you haven't connected that particular service.
