Another of Domino's magic numbers : 42220

While cleaning up my mail file (hovering at 2 GB) I dropped my full text index on the server. I forgot to recreate it. When checking the log files I discovered one of Domino's magic numbers:

31.05.2005 12:17:40   Warning: Agent is performing full text operations on database 'test.nsf' which is not full text indexed.  This is extremely inefficient.
31.05.2005 12:17:40   Full Text message:  index of 42220 documents exceeds limit (5000), aborting: Maximum allowable documents exceeded for a temporary full text index
31.05.2005 12:18:25   AMgr: Error executing agent 'Move Document Around' in 'test.nsf': Maximum allowable documents exceeded for a temporary full text index

So you can't have more than 42220 documents if you want to full text search an database without a fulltext index. But who would want to do such a thing anyhow. Harddisk space is growing faster than CPU or transmission speed.
