Using a content Search class

Question

The search class below works. When I try to pass the String array
into a servlet using:
Searcher search_instance = new Searcher();
String[] servlet_array = search_instance.getRes();
it always fails. When I configure the class as a stand-alone
class (with the 'getRes' method called from a 'main' method. It
works. Also, when I tried to convert this code into a servlet,
it fails as well. I simply want to return search results to a
browser using a servlet or JSP. Has anyone solved a similiar
problem?

Hi,
Please try to use the following query text.
(CONTAINS(PlacesId, 'a2ce9dd7-f801-4403-affb-1944bf253255') OR (PlacesId > ''))
Here are two materials for you to take a look at:
