since we can have unlimited nesting levels category tag > parent tag > child  1 tag / chid 2 tag  etc , in a future version may be you can make it possible to do complex serches using child tags.  I think now you cannot search using two child tags ( 3rd level tags) or click two child check boxes at the same time. .

Thanks Asaf, it was my mistake. 'OR' will do the thing I want to do. 

May be this should go to help but I do not want to open a new thread, I have troble downloading the new beta version, all I get is the current .17 version from this link , http://www.myphotoindex.com/Home/tabid/37/Default.aspx.

May be it is a problem with my download manger, but any help would be appreciated. Thanks

Srinid

have you managed to download the beta ?
