Is there a way to specify weightage (find boosting) to catalog content properties? The Find UI only shows 4 properties by default : title, content, summary and document content. These all refer to page properties rather than catalog properties. Can additional properties be added here? Or can we do something in code to assign weightage to catalog content properties?
You can boost with filters using BoostMatching:
That will allow you to provide an expression to a catalog content property, and provide a boost weighting to this.
