API version 3
Function public IfdDelta [] get_delta_of_concepts (                                                  String session_id,                                                   String search_criteria,                                                   String timestamp,                                                   String[] language_codes                                                   String[] context_guids) throws IfdServerException

EXPRESS Heading Query function get_delta_of_concepts(                 search_criteria,                  timestamp : STRING;                  language_codes,                   context_guids : LIST OF STRING): IfdDelta;

The function investigates target population and collects all concepts and their relationships changed after the specified date/time stamp in domain of IFD population limited by relationship contexts, representation languages and search criteria..

Input:
 * String search_criteria - string pattern to apply to the concept names to filter them. The pattern can include the whole interesting name or its part (letters are case insensitive) and a number or matching characters;
 * String timestamp – date/tiem stamp in format ‘YYYY.MM.DD hh:mm:ss’ specifying a moment to search for changes after it;
 * String[] language_codes – list of languages specified by their codes to limit the changed concepts representation (normally it shall be all languages defined in IFD population local copy);
 * String[] context_guids– list of context global unique ids – domains of relationships

Return: IfdDelta - Structure that collects updated/added IFD concepts and their relationships in scope of specified languages, contexts and name pattern (see IfdDelta description).
