ALSearchInput is used as the input field when searching for objects across Alation. This should be the search field used universally across the top nav of the product and supports the co-branding use case.
This search input behaves differently than a filter (e.g. the search bar on My Inbox or on PlatformTable) as it works with ElasticSearch to retrieve results.
