Global Search is the latest and useful feature in Microsoft Dynamics CRM 2015 , allowing users to query across multiple entities.

1. A query Box on top navigation
2. Global search entities need to be configured first (default contain Account, Contact, Lead, Opportunity, User, Activity, Case )

Enter search query to get result from multiple entities of default global search

We can also filter from default configured global search

We can modify global search entities : Settings > Administration > System Settings

Once entities are configured we need to add fields in quick find view Settings > Customizations > Customize the System > Entity > Views

add columns and filters

Publishing the view change. Hope this was help full.
