thanks dieter for your suggestion.  i did as told, and i still got 
ReadConflict even when there's no write to thezodb (i'm 95% sure since 
there was no activity in the Undo, and it was the editors break time 

after i run Update catalog, there's no such error in either of the index.

i want to use ZCTextIndex for the relevance, and some other features.. and 
would not want to use TextIndex, unless really really have to.
