What exactly is the problem? The standard idiom nowadays for
iterating through a List is what you're using in "for (Field field :
...)". I haven't used an iterator for a long time.
But perhaps your iteration code is working and the problem is in your
search code. The javadoc for search(query, n) finds the top n hits
for the query. Maybe you need a larger number than 1.
