1. Correct

2. Use the  beginDate supplied in the method. This is in Utc. You should be able to write query to return records that have changed since this date.

3. You can continue to pass just the QueryString in the QueryString property of the SearchDocument and platform will construct the full url based on TabId and ModuleId.

Have a look into my blog here:  http://www.dnnsoftware.com/community-...

more to follow soon.

So here is complete example, for everyone for who it is easier to "follow-by-example". 

1. I first create a seperate class called StudentsController (my view is called Students)
2. Then inherit from ModuleSearchBase
3. Then I have a datatable that is being filled with my student data from the database 
4. Then inside GetModifiedSearchDocuments, I loop through all the records in the datatable and create a searchDoc for each.
5. Then searchDocuments is the collection of the searchDoc('s)

DataTable tbl = new DataTable();
tbl = DocumentData();
foreach (DataRow r in tbl.Rows)
{
Dictionary<string, string> keywords = new Dictionary<string, string>();
keywords["MiddleName"] = r["MiddleName"].ToString();
IEnumerable<string> tags = new string[] { r["Name"].ToString(), r["Surname"].ToString(), r["RegistrationNumber"].ToString() };
var searchDoc = new SearchDocument
{
UniqueKey = String.Format("Student{0}", r["StudentID"].ToString()),
QueryString = String.Format("id={0}", r["StudentID"].ToString()),
PortalId = modInfo.PortalID,
Keywords = keywords,
Tags=tags,

searchDocuments.Add(searchDoc);
