示例1: Index
/// <summary>
/// This method indexes the content that is sent across to it. Each piece of content (or "document")
/// that is indexed has to have a unique identifier (so that the caller can take action based on the
/// document id). Therefore, this method accepts key-value pairs in the form of a dictionary. The key
/// is a ulong which uniquely identifies the string to be indexed. The string itself is the value
/// within the dictionary for that key. Be aware that stop words (like the, this, at, etc.) are _not_
/// indexed.
/// </summary>
/// <param name="txtIdPairToBeIndexed">A dictionary of key-value pairs that are sent by the caller
/// to uniquely identify each string that is to be indexed.</param>
/// <returns>The number of documents indexed.</returns>
