Class FieldExpression

    java.lang.Object
      com.google.appengine.api.search.FieldExpression

    public class FieldExpression

extends java.lang.Object

Represents an expression bound to a returned Field with the given name. FieldExpressions are added to a `SearchRequest` to request an expression is computed and returned as the named Field value. For example,

       FieldExpression.newBuilder()
           .setName("snippet")
           .setExpression("snippet(\"good story\", content)")
           .build()

binds a snippet expression to a Field named "snippet", which will be returned in each search result. In this case the returned "snippet" Field will contain a HTML value containing text snippets of the "content" field matching the query "good story".
