We are using the com.day.cq.wcm.foundation.Search object to do basic full text searches in our site and I've got a question about how it determines what value to assign to Search.Hit.excerpt. We've got the following properties defined for excerpt properties: text, jcr:description, history:caption, and history:description. If the search terms are found in any of those properties the excerpt is returned correctly, but if they're not found in those properties the excerpt returned is the last 60 characters from the history:description field. Is this expected behavior for the search?
