If by "search" you mean "filter" - i.e., read the capture file, and 
discard all packets not to or from that AP - that'd be

	tethereal -R "wlan.sa == {address}" -r {input file}

(unless, of course, you've upgraded to the latest version, in which case 
it'd be "tshark", not "tethereal" - see http://www.wireshark.org/). 
{address} here would be the MAC address of the AP and {input file} the 
file you're reading.
