The Search box in the header has different search options: All and Taxonomy.
All finds all content that includes the search term.
Taxonomy only searches for terms in one of the vocabularies and returns the matched terms.
The search functionality is aware of the content type you’re viewing: When you are viewing a page (“Page” content type) you will get an additional option to search only page content.
Clicking on the Search button when the search field is empty will lead to a faceted search page.
Some pages provide the option of faceted search in a separate block on the left of the page. Faceted search can be used to filter the nodes of a content type (e.g. References) To use the faceted search:
- Fields with less than 20 terms show up as a list. Click on a term to restrict results for this term
- Fields with more than 20 terms also provide an auto-complete search box. Fill in the term and press enter or else select from the list
- You can remove a filter by clicking on the (-) sign next to a selected term
- You can filter the content based on multiple fields
