You can access and modify your Site Preferences from the menu available underneath your Name in the upper right corner:
After clicking Preferences, the Preferences which you can manage are divided into several categories.
Here we'll take a quick look at Searching Options:
Setting Search Auto-Redirect to Yes will take you directly into a contact's record, if their record is the only one that meets the parameters of a search you've just run.
After making any changes to this option, click Save Preferences in the upper right corner of the Search Options widget and your preferences will be saved.
