How much is the retrieval fee when applying for a patent?

The "search report fee" is as follows: in a patent application, an invention has to go through procedures such as preliminary examination and substantive examination. In the substantive examination, the examiners have to check the patents of 7 countries and 2 organizations and whether there are the same patents in 2000 domestic and foreign journals and magazines, so the amount of access is very large. We have to pay the examiner's labor, so we have to charge a "retrieval report fee". For the utility model, there is no "search report fee" because there is no substantive examination.
