Oh, thank you, so I finally found what you need - knowing the last modified
date, for printing it in results, for sorting results by date, for limiting
results to given dates. Am I right?
Hmm...this would be not a five-minutes hack to do it...we store Last-Modified
header in SQL DB and later send it back...so we can't store "date" meta there.
But we can add one extra field into SQL DB, for just storing "date" meta.
Later, in a process of parsing delta files, ranks calculation and so (which
is done before index finishes, or explicitly by running index -D),
Last-Modified fields gets read from SQL DB and stored into binary file
named "lastmod", format of the file is described in lastmod.h (or .cpp)
Ok, I will include it in 1.1-devel TODO, we can't do it in 1.0 because this
needs database changes.
