* Usage: php updateSearchIndex.php [-s START] [-e END] [-p POSFILE] [-l LOCKTIME] [-q]
* Where START is the starting timestamp

- * POSFILE is a file to load timestamps from and save them to, searchUpdate.pos by default
- * LOCKTIME is how long the searchindex and cur tables will be locked for
+ * POSFILE is a file to load timestamps from and save them to, searchUpdate.WIKI_ID.pos by default
+ * LOCKTIME is how long the searchindex and revision tables will be locked for
* -q means quiet
