I am trying to use a Filter Index Reader to provide access only to the subset of my archive for which a certain field contains one of a given list of values.
The idea is to create a special term for this field that means 'any term in the list', and add an 'AND' clause to every query, to enforce the condition. I override the seek() and next() methods of FilterTermDocs. In the seek(Term t) method I check if t is my special term. If it is, I initialize an instance variable in the FilterTermDocs, with an Iterator over my List. I then call super.seek(s) for a term 's' which has the same field name and a value which is the next element from the interator. In the next() method, If super.next() returns false, but the iterator is there and has a next element, I call super.seek(s) for the next element and try again. The problem is the although my seek() method is being called, my next() method is not. Thus I never get to iterate through my list, and only receive results corrasponding to its first element.
