Okay, but how am I going to squeeze between two customs? I guess you'd have to
store as a compare against either side?
*EDIT*
There is also the problem that all compares are done based on ScoreDocs that
index into a single ord array by doc. The previous pq's ScoreDocs will not
compare right - they won't index into the ord array for the current Reader -
they are indexes into the array for the previous Reader. This is what made me
give up on single pq earlier.
*EDIT*
I guess we put them on the ScoreDoc like we do the values for multisearcher?
Then we could use a PQ like FieldDocPQ that used ords rather than vals?
