Boosting or Excluding Schema Fields
Administrators can add exclusions or boosts to an individual schema or add them to select fields within that schema. Use boosts to determine how prominently the entire schema or schema-specific fields display when returned in search results. For example, without intervening factors, a schema field that has a boost value of 1.4 will rank higher than another schema field with a boost value of 1.2 in the returned results.
Use exclusions to omit schema-specific fields from the search index. The content in these fields don't display in search results.
These boosts and exclusions apply to elements that match the field name anywhere in pages associated with the specified schema (e.g., at the page root level, in an embedded component, or in a page presentation).
