- com.google.appengine.api.search.FieldExpression

```
public class FieldExpression
extends Object
```
Represents an expression bound to a returned Field with the given name. FieldExpressions are added to a QueryOptions, to request an expression 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".
