Two FTS tables? One with the Porter stemmer, for search, one without, to
build the auxiliary tables?
Yeah, that is the last option, if nothing else works. For a small set
of documents the extra processing time might be ok but for a larger
set of documents building the FTS tables twice might be

Hi,
The documentation page of the VACUUM command says that The VACUUM
command may change the ROWIDs of entries in any tables that do not
have an explicit INTEGER PRIMARY KEY. So what are the possible cases
