[Xapian-devel] term duplication among index tables

[Peter A. Friend]

Greetings all,

I have been looking into using Xapian to provide search for email. I  
have to be very careful about indexing overhead, and I notice that  
several of the tables use term strings as part of the key or data. I  
was wondering if there is a performance or complexity reason for not  
having a separate table mapping term strings to unique numbers, which  
could then be used in the other tables. Is this something that has  
been considered previously and discarded as unworkable, or do you  
think it may be worth pursuing?

Cheers,

Peter
