Two ideas here:

1) Include word counts in your indexes. If you are doing an AND condition 
check the word counts of each word and then get a verse list for the least 
used word, then search those verses for the other words.

2) When checking that verses fall in the correct range for a word with lots 
of hits, use something like a binary search to establish the boundaries in 
the index. Then just use the index entries between the boundary records.
