Adding Field Boosts
Field boosts increase how prominently individual fields display when returned in search results. For example, without intervening factors, a field that has a boost value of 1.4 will rank higher than another field with a boost value of 1.2 in the returned results. The boosts apply to elements that match the field name anywhere in the page (e.g., at the page root level, in an embedded component, or in a page presentation).
Note
We recommend setting the boost value within the 1.0-4.0 range or, as
higher values tend to introduce additional variances in results, consider setting
the boost value within the 1.0-2.0 range. Boosting is also dependent on how often
the term occurs in the boosted field.
