UPnP Media Server : I am implementing the search action as follows. The following code doesn't support the priority logical operation using the brackets, but I could check Sony's UPnP AV player, TA-LV700R, with the search function.

bool SearchCriteriaList::compare(ContentNode *cnode, SearchCapList *searchCapList)

{

  int n;

  int searchCriCnt = size();

  // Set compare result

  for (n=0; n<searchCriCnt; n++) {

    SearchCriteria *searchCri = getSearchCriteria(n);

    const char *property = searchCri->getProperty();

    SearchCap *searchCap = searchCapList->getSearchCap(property);

    if (searchCap == NULL) {

      searchCri->setResult(true);

      continue;

    }

    bool cmpResult = searchCap->compare(searchCri, cnode);

    searchCri->setResult(cmpResult);

  }

  // Eval only logical ADD operation at first;

  SearchCriteriaList orSearchCriList;

  for (n=0; n<searchCriCnt; n++) {

    SearchCriteria *currSearchCri = getSearchCriteria(n);

    if (n<(searchCriCnt-1)) {

      if (currSearchCri->isLogicalAND() == true) {

        SearchCriteria *nextSearchCri = getSearchCriteria(n+1);

        bool currResult = currSearchCri->getResult();

        bool nextResult = nextSearchCri->getResult();

        bool logicalAND = (currResult & nextResult) ? true : false;

        nextSearchCri->setResult(logicalAND);

        continue;

      }

    }

    SearchCriteria *orSearchCri = new SearchCriteria(currSearchCri);

    orSearchCriList.add(orSearchCri);

  }

  // Eval logical OR operation;

  int orSearchCriCnt = orSearchCriList.size();

  for (n=0; n<orSearchCriCnt; n++) {

    SearchCriteria *searchCri = getSearchCriteria(n);

    if (searchCri->getResult() == true)

      return true;

  }

  return false;

}

TA-LV700R : I checked the search function with the UPnP Media Player and the UPnP Media Server for MythTV using the code. At first, the player couldn't read the stream, but I could fix the problem to changed the mime type for the protocolInfo from */* to video/mpeg as follows. I can see the movie contents in the MythTV using the UPnP Media Player now :-)
