Under further information for "filtering while capturing":
http://wiki.wireshark.org/CaptureFilters
it gives the example in the docs page:
http://www.wireshark.org/docs/wsug_html_chunked/ChCapCaptureFilterSection.html
tcp port 23 and host 10.0.0.5
if you type in tcp port 23, it gives the error, but if you use tcp.port==23, it doesn't
the correct syntax would have been tcp.port==23 and ip.src="">

I suppose you mean Display filter. Display filters work online(while capture is going on) and offline. Its syntax is different from capture filters. What does WIKI say about the syntax?
