This is in reference to the Nutch "content" segments
(segments/<timestamp>/parse_text, etc.), not the segments of a Lucene
index.

I am considering using SegmentMerger to combine a large number of
fetch segments into a single huge segment. Will doing so create a
performance problem when generating page summaries at search time? If
so, is there a recommended maximum size for one of these segments?

Thanks,
Charlie
