Gets the version ID of the parent inclusion URL.
HRESULT GetParentScopeVersionId( LPCWSTR pszUrl, LONG *plScopeId );
[in] A string containing the current URL.
[out] Returns a pointer to the version ID of the parent inclusion URL.
Returns S_OK if successful, or an error value otherwise.
Use this method to determine if the indexer is aware of a change in a data store or scope (e.g., a data store is removed and then re-added to the index), potentially requiring a new push of the hierarchical parent of the store's URL.
This ID will most likely change if a scope rule is removed and then added back. This method returns S_FALSE if no parent inclusion URL was found.
