[Parameter] Short Field Boost [Fields API Attribute Name] short_field_boost [Description] 
This relevancy boost compensates for text in short documents that have fewer opportunities for text matches and may otherwise rank lower in results than they should. Use 'moderate' for typical text fields such as the abstract or body of an article. Use 'high' for very short fields like title or keywords. Use 'none' for non-text fields. We strongly recommend that you follow changes to the short field boost with a full reindex.
