Sorry, I misunderstood the problem. My mistake. While not optimal and rather expensive space-wise, you could have - in addition to existing keyword field - a field for each category. If the document being indexed is in category A, only add the text to the catA field. Now do MoreLikeThis on catA. This assumes you know the categories at index time, of course. Redundant but workable.
