Hierarchical Table Commands in MDM API

Question

Hi,
I found only RetrieveLimitedHierTreeCommand,RetrieveLimitedHierChildrenCommand in MDM API for hierarchical tables.
So how can we add a child or a sibling, delete a child or sibling to the nodes of the tree.
Can anyone please give me links or some documentation on how to proceed with this.
The other problem we are facing when retrieving the children using RetrieveLimitedHierTreeCommand
When we add a search on the command it does not retrieve the children. it says the children for the level one node are null but if i donto set search it retrieves the children for all the nodes.
Is there any specific setting that has to be done for using the search.
Please let me know
Thanks,
Padmaja

Hi Greg,
I am adding the code snippet below. Can you please look into this and check if there are any problems
RetrieveLimitedHierTreeCommand hr=new RetrieveLimitedHierTreeCommand(conAccessor);
Search ser=new Search(repoSchemacmd.getRepositorySchema().getTable("New_Code").getId());
FieldId fldId =repoSchemacmd.getRepositorySchema().getTableSchema("New_Code").getField("New_Code").getId();
StringValue fldVal = new StringValue("G0440");
ser.addSearchItem(new FieldSearchDimension(fldId),new TextSearchConstraint(fldVal.getString(),TextSearchConstraint.EQUALS));
hr.setSearch(ser);
ResultDefinition rd=new ResultDefinition(repoSchemacmd.getRepositorySchema().getTable("New_Code").getId());
rd.setSelectFields(repoSchemacmd.getRepositorySchema().getTableSchema("New_Code").getFieldIds());
hr.setResultDefinition(rd);
hr.setSession(userSessionID);
try {
     hr.execute();
} catch (CommandException e) {
    e.printStackTrace();
When i execute this part of code and get the children. i get the children as null.
Thanks,
Padmaja
