Examples
C#
String owner = "My Corporate";

// create the equal filter - this will only match records where
// the 'owner' column is equal to the string defined above
EqualFilter ef = new EqualFilter("owner", owner);

// the index defines the table we will query (myTable) and the 
// columns we want to retrieve (the columns were defined when
// the index was created 
Index idx = myTable.Indexes["my_index_name"];

// we must begin a transaction before we can perform a query
myTransactionalRepository.BeginTransaction();
Console.WriteLine("Warehouses where owner is '{0}'", owner);

// 
// here's where we actually use the EqualFilter - as part of the 
// query. note that we can iterate through the returned records
// using an enumerator.
// 
foreach (Record r in idx.Query(new ColumnFilter[1] { ef }) {
    Console.WriteLine("\t{0}, phone {1}", r["address"], r["phone"]);
}

// ... we've finished the query so we should end the transaction
myTransactionalRepository.EndTransaction();
