(BThe (English) docs provides little information about the -Y option.
(BI found out that I can use -Y to do selective updating of an index
(Bwithout having an entire directory structure rescanned. For example,
(Bif I have the following directories:
(BPart of a single namazu index, I can run 'mkmnz -Y 2001-09' to update
(Bthe index for any files in 2001-09, but preserve the index information
(Bfor 2001-07 and 2001-08 because I know 2001-09 will be the only directory
(Bwith any changes.
(BMy question is, "Is this a proper use of this option?" It appears
(Bto be so, but the description of it does lead to some doubt since
(Bthere is --update option with sematics I am not sure about. Also,
(Bis the method better for overall performance since namazu is not
(Bhaving to scan the entire file set for changes? Will there be any
(Bsearch performance degradation using this method of updating?
