Thank you for your very quick reply - and for your solution, that works perfectly well.
Still, I wonder why this simple and straightforward syntax "web OR NOT(russia)" needs some translation to be processed correctly... >From the many related posts I read before asking my question, I know that I'm not the first one to be puzzled by this behavior. Wouldn't it be a good idea to modify the (Lucene, I guess ?) parser so that the subsequent processing would produce a correct result ?
