URL Query Sql Expression directly to REST issue

Question

Hope this is simple.  When I browse to my Server Service URL
http://gis.myserver.gov/ArcGIS/rest/services/Parcel_Layers/MapServer/50
and enter a "where" expression:

this works -
TAX_ID = '253-004' AND NOT TAX_ID = '253-005'

this does not work -
TAX_ID = '253-004' OR TAX_ID = '253-005'

It seems to understand "AND NOT" but doesn't understand "OR" - why?
I want to select two parcels at one time - with a valid sql expression.
Later I will pass this string from actionscript.  Thanks for any ideas.

Robert - you are good - thank you!Dan,

You can always use the IN operator instead:query.where = "TAX_ID IN ('253-004', '253-005')";

Thanks for taking a shot Keith.  It should work - but, doesn't!  Sql server queries are fine.
It's a simple rest query:

query.where = "TAX_ID = '253-004' OR TAX_ID = '253-005'";

The flex API documentation for the class where property states:
"Any legal SQL where clause operating on the fields in the layer is allowed."

Well, "OR" is legal - I'm stumped.
