1. CCN offers two search tools, which you may choose either one (search by keyword or by category) to list the items in conformity with your requirement. You may also choose single or multiple filters from No.1-4 to narrow your focus. When you choose "and", it means the following condition is prerequisite, "or" means the following condition is additional and not essential. Whereas, you can click on the search button directly by leaving these filters blank.
E.g. if you search apple suppliers information with product pictures and email, you can chose:

If you want the suppliers information with product pictures or email, you choose:

Also you can choose any other combinations of filter groups as you need, e.g.


2. If your search results are unsatisfactory, try to use fewer words, for example: use "ink" or "cartridge" instead of "printer ink cartridge".

3. Do not use specific characters such as "+", "?", "\" or "<" etc.

4. Avoid using country/region's name in your search, for example: use "apple" instead of "China apple".

5. Avoid using the word "seller" or "buyer" in your search, for example: use "apple" instead of "apple seller".

6. Search one product at a time.

7. If you didn't get the needed result, please try again by fewer filters.
