Problem with searching using the DisMaxHandler

[Brian Carmalt]

Hello all, 

I have defined a DisMax handler. It should search in the following
fields: content1, content2 and id(doc uid). I would like to beable to
specify a query like the following:
        (search terms) AND ( id1 OR id2 .. idn)
My intent is to retrieve only the docs in which hits for the search
terms occur and that the docs have one of the specified ids.

Unfortunately, I get not document matches. 

Can any one shed some light on the What I am doing wrong?   

Thanks, 
Brian
