ok, woops.. it does work on the old 440 db. I just didn't know that the box lebeled 'Show Execution Plan' meant it was only going to show me what was going to happen and not actually do it. So this time I ran these items again:

delete dbo.SearchItemWordPosition
delete dbo.SearchItemWord
delete dbo.SearchWord
delete dbo.SearchItem

And all tables now show zero entries except for SearchItemWord, which now shows 59 for some reason... though when I click inside it, it has no records.. go figure?

So.. I'll go and try this on the 441 site once the host has reset IIS.

I'll report back the results

Before turning the search scheduler back on, try re-indexing manually once and see how long that takes.

Ok.. I've done it on the 441 db now with this result:

SearchCommonWords
dbo
8/10/2006 5:30:14 PM
PRIMARY
369
SearchIndexer
dbo
8/10/2006 5:30:14 PM
PRIMARY
1
SearchItem
dbo
8/10/2006 5:30:14 PM
PRIMARY
4
SearchItemWord
dbo
8/10/2006 5:30:14 PM
PRIMARY
65
SearchItemWordPosition
dbo
8/10/2006 5:30:14 PM
PRIMARY
0
SearchWord
dbo
8/10/2006 5:30:15 PM
PRIMARY
0

I'm confused why there are still a few records listed for SearchIndexer, SearchItem and SearchItemWord (I understand SearchCommonWords is not part of this). I'm mainly confused that when I click to examine the contents of these items, there are no records listed.

Is that possibly a clue to the duplicate key errors that occur and caused this whole mess? Some sort of buggy data hiding in there perhaps?

I'll do a manual index right now and time it - There are a few portals on here, but not a lot of pages so I don't expect much. I've got minimum word length 3 and common words and numbers included.

Result: 2 minutes.  Now I'll check the tables and see what happened:

SearchItem
dbo
8/10/2006 5:30:14 PM
PRIMARY
508
SearchItemWord
dbo
8/10/2006 5:30:14 PM
PRIMARY
17530
SearchItemWordPosition
dbo
8/10/2006 5:30:14 PM
PRIMARY
41001
SearchWord
dbo
8/10/2006 5:30:15 PM
PRIMARY
6147

That's less than was there before. hopefully it got rid of the buggy bits. I'll re-enable the scheduled task but set it for a once-daily run instead of the 30 minutes it defaults to.

Thanks for the advice.. and any further comments are still keenly observed!

Rob
