Debbie,
it depends on your Mapserver version, there was a bug that not more than
2 conditions could be nested with And or Or. 4.8.1 should have that
fixed for sure.
See this for more details:
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1277
Btw officially it is Or and not OR, and even more officially it should
be ogc:Or
Best regards,
Bart

I did a quick search but couldn't find a filter encoding that allowed an
OR to be used to find more than 2 features.
I found this for 2 features:
http://www2.dmsolutions.ca/cgi-bin/mswfs_filter?&VERSION=1.0.0&SERVICE=W
FS&REQUEST=GetFeature&TYPENAME=popplace&Filter=<Filter><OR><PropertyIsEq
ualTo><PropertyName>NAME</PropertyName><Literal>Sydney</Literal></Proper
tyIsEqualTo><PropertyIsEqualTo><PropertyName>NAME</PropertyName><Literal
Digby</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>NAM
E</PropertyName><Literal>Halifax</Literal></PropertyIsEqualTo></OR></Fil
ter>
and then tried this for 3 features:
http://www2.dmsolutions.ca/cgi-bin/mswfs_filter?&VERSION=1.0.0&SERVICE=W
FS&REQUEST=GetFeature&TYPENAME=popplace&Filter=<Filter><OR><PropertyIsEq
ualTo><PropertyName>NAME</PropertyName><Literal>Sydney</Literal></Proper
tyIsEqualTo><PropertyIsEqualTo><PropertyName>NAME</PropertyName><Literal
Digby</Literal></PropertyIsEqualTo><PropertyIsEqualTo><PropertyName>NAM
E</PropertyName><Literal>Halifax</Literal></PropertyIsEqualTo></OR></Fil
ter>
But it didn't work. Any examples out there for how to do this?
Thanks in advance.
