Not sure what you mean here: If I compose a mail using gmails web interface and type a prefix of someone's name I will get this contect as a suggestion. My point was that using your tool, I did not get a contact suggested for all prefixes. > > The time lookups take seems to depend on how many matches there are: > > > > ------------------------------- > > time nbook Suvayu > > 1 unique email addresses found for `Suvayu' > > fatkasuvayu+li...@gmail.com Suvayu Ali > > > > nbook Suvayu 0.04s user 0.01s system 95% cpu 0.050 total > > ------------------------------- > > time nbook Justus > > ... > > > > nbook Justus 0.21s user 0.07s system 11% cpu 2.484 total > > ------------------------------- > > Yes, I noticed this too when I searched for the more common names.

This means you go through some condidate as often as you index contains mails from/to him. What one really wants is to ask the database to do something like "SELECT name,email from RECIPIENTS_OR_SENDER" where RECIPIENTS_OR_SENDER is some imaginary list that stores a set of contacts. Bottom line: One would have to change the layout of the underlying database (not likely) or do regularly update some cache and only work on that.

As mentioned before, I think you invalidate the Database object concurrently while your long-running algorithm goes through all messages. Xapian doesn't handle concurrent access to the index like a normal™ database would. This means you are notified by this error that some changes were detected. Maybe the error message should be more telling here though. Teythoon? > > Anyway, have fun hacking notmuch!
