To refresh the search database do the following:
cp moweb.dbm moweb.dbm.archive
to cover for mistakes. Then to make the new database:
mkformula.pl > moweb.dbm
Try out the new database from the search page to make sure
everything went well. To count the number of entries do this:
cat moweb.dbm | wc -l
The number of lines in the database will be printed out.
If the new database isn't correct you can recover the old
version by
cp moweb.dbm.archive moweb.dbm
