How to search to files based on the metadata of the category in CS

Question

Hi,
Can any one tell me how to search the files in the content services based on the metadata of the Category,I know how to search based on the Category using
public static void attributSearch(String searchString)
throws FdkException, RemoteException, Exception
// get the Manager instances
SearchManager sem = s_WsCon.getSearchManager();
CategoryManager cat = s_WsCon.getCategoryManager();
CommonManager cm = s_WsCon.getCommonManager();
FileManager fm = s_WsCon.getFileManager();
Item folder = fm.resolvePath("/idc/workspaces/BoardMembersProject", null);
AttributeRequest[] catAttr =
WsUtility.newAttributeRequestArray("ProjectCategory");
// create AttributeRequest to retrieve CATEGORIES attribute
AttributeRequest[] catClassAttr = WsUtility.newAttributeRequestArray(
Attributes.CATEGORIES, catAttr);
// define search options
NamedValue[] nv = WsUtility.newNamedValueArray(new Object[][] {            
{ Options.SEARCH_VERSION_HISTORY, Boolean.TRUE },
{ Options.RETURN_COUNT, new Integer(100)
// get search expresiion
SearchExpression seExp = new SearchExpression();
// searchString ="ProjectCategory";
Item[] item = cat.getRequiredCategories(folder.getId(),catClassAttr);
seExp = new SearchExpression();
NamedValue[] attributes = item[0].getRequestedAttributes();
seExp.setOperator(FdkConstants.OPERATOR_HAS_CATEGORY);
seExp.setRightOperand("["+item[0].getName()+"]");
// search documents
NamedValue[] result = sem.search(seExp, nv, null);
// search result display
for (int i = 0; i < result.length; i++)
if (result.getName().equals(Options.SEARCH_RESULTS))
Item[] resulItem = (Item[]) result[i].getValue();
WsUtility.log("Kveni",resulItem);
if (resulItem != null)
for (int j = 0; j < resulItem.length; j++)
WsUtility.log("File " +resulItem[j].getName());
But how do one search Based on the attributes of the category??
thanks

Download the PM accelerator kit appropriate to your environment, and check out the TestSearch2.java example.

Essentially you need to lookup the internal names of your category attributes, as well as have the internal name of your category class.
categoryClassName = ...; // e.g. AHC_XXX
attribute1name = ....; // e.g. CUSTOM_MYBOOLATTR
you then create a normal search expression such as
String attribute1Operand = "[" + categoryClassName + FdkConstants.SEPARATOR + attribute1name + "]";
SearchExpression expr1 = new SearchExpression();
expr1.setOperator(FdkConstants.OPERATOR_EQUAL);
expr1.setLeftOperand(attribute1Operand);
expr1.setRightOperand(Boolean.TRUE);
