Gmail – How to create filters in Gmail with “OR” condition in “Has the words”

I don't think Gmail filters will work with parentheses like that. I think you'll need to negate every term.

subject:"USB 3.0" -Notebook -"2,5" -Seagate -RAID -HDD -TB -Hub -Bus -WD -"Western Digital"

All that said, filters are generally just saved searches, so try searching for "USB 3.0" -Notebook and keep adding terms until you get back the results you want, then save it as a filter.

You can use Google Script to search the Reply-To: field in the header and route messages to different folders if they do not match the domain in the From: field.

Here's a sample snippet for searching the Raw Header of a message via scripts.

function searchGmailByMessageHeader() {
  var threads = GmailApp.getInboxThreads();
  for (var t in threads) {
    var headers = threads[t][0].getRawContent().split("\r\n"));
    for (var h in headers) {
      if(headers[h].match(/Reply-to.*?DOMAIN_NAME/) {
      // DO SOMETHING
      break;
    }
  }
}
