# 3606 Text Indexes Containing Words Longer than Word Length Can Experience Corruption

I have jsut encountered a strange problem. Whenever I run a Optimize Table, one of my text indexes gets corrupted. If I run a Verify Table after the Optimize, I get the following errors:

Verification of the table Parts started at 2012-07-24 20:53:42.0189
Verification error for the index Text_Info in the Parts table file D:\Temp\EDB_Test\ANSI\ees4-demo1\Parts.EDBIdx (Invalid index page 2477 key page pointer (1207961346)) - Not Fixed
Verification error for the index Text_SearchValues in the Parts table file D:\Temp\EDB_Test\ANSI\ees4-demo1\Parts.EDBIdx (Invalid index page 3493 key page pointer (487129088)) - Not Fixed
Verification of the table Parts ended at 2012-07-24 20:53:42.0522

Before the Optimize, there were no errors on Verify.


Comments Comments
The basic problem was that the key size calculated internally by the engine for text indexes was not properly taking into account a Null flag byte, and this would cause the text index keys to be incorrectly shifted by one byte. Unfortunately, this would not surface as an issue unless the word being indexed was longer than the text index word length and needed to be truncated. In such a case the problem would be exposed. Please see the release notes for 2.10 for a script that you can run on any database to automatically repair the text indexes and ensure that the database tables with text indexes are working properly.
