When SaveSectionSize is set to yes,
indexer stores additional information about section size
(messured in number of words)
for every document section. Using section sizes makes it possible
to generate better score values at search time by taking
into account frequency of every search query word in its section.
Setting SaveSectionSize to no
makes search index size about 10% smaller.
This slightly improves search performance, but makes search quality worse.
SaveSectionSize must have the same value in
indexer.conf and search.htm.
The default value is yes.
mnoGoSearch version 3.3.0. Versions prior
to 3.3.0 did not store section sizes.
