Schema

Schema refers to the structure or format of a document or set of documents in a search engine index. For example, an example news article schema might have the following fields: title, subtitle, author, sections, body, and publication date. This structure is extracted from the web page HTML by and filed away in this format in the search engine index.

In Swiftype

By default, Swiftype’s web crawler extracts the following fields to populate the index schema: title (from the page’s <title> tag), body (from the page’s content),
and sections (from the page’s <h1> to <h6> tags).

Once these fields are indexed site owners can customize the search interface to render these pieces of information in the autocomplete or search results page. Swiftype also allows site owners to customize their website schema with custom meta tags.
