How to retrieve message IMAP

What is the difference between the fetch command and the search command in IMAP?

I am trying to get the messages in my inbox, I use the following command to retrieve the UID:

sb = receiveResponse("$ UID SEARCH ALL\r\n");

then I use this command to fetch a particular message header:

sb = receiveResponse("$ FETCH " + number+ " BODY.PEEK[HEADER.FIELDS (From Subject Date)]\r\n");

Does the fetch command use the UID to get the message header or does it use the message number?

If it uses the message number, how do I retrieve the message numbers?

Use UID FETCH to fetch by uid. Use just FETCH to fetch by message sequence number.

If you want to just download all messages in the INBOX folder, all you need to do is

FETCH 1:* BODY.PEEK[HEADER.FIELDS (From Subject Date)]
