Convert Home Search Bar to Full Search

[theryankelly]

Describe the feature. What should a user be able to do?
The current home page allows users to filter datasets through the search box. Users should have the ability to search for all content that includes Profiles and Gallery content. For example, this may take the form of a wildcard search pulling related text from a gallery viz narrative.

Why do we need this feature?
Enable users to find additional content from the home page.

Additional context
Will also note issue #371 that looks to add the ability to search by type of content.
The current search box is more of a filter that could change the language to reflect that if we don't implement the ability to search all content.
