keepnoise not working

[bart]

I created an index in the following manner:
<sql "set keepnoise=1"></sql>
<sql "set delexp=0"></sql>
<sql "set addexp='\alnum{2,50}'"></sql>
<sql "set addexp='[\alnum\x80-\xff]{1,70}'"></sql>
<sql "create metamorph inverted index xwgaztxt
on worldgaz(name\altnames\adm1\adm2\adm3\cc\country,geo,pop)"></sql>


There are country codes in the cc field. When I search the index non-noise country codes it works fine , but for US and IT it returns nothing.
www% tsql "set indexaccess=1;select * from xwgaztxt where Word = 'gb'" | more

Whats up with this?

Is there a keeplips=1 option as well as keepnose?

Anyways Thanks , maybe doc clarification would be in order here. I read the tutorial page on this ( http://www.thunderstone.com/texis/site/ ... ssues.html ) and that was how I decided to use <sql "set">
