[Xapian-discuss] How to search URL field (unique Q key)?

[oscaruser at programmer.net]

Hi James,

If I'm not mistaken, the approach of printing all of the Q terms basically dumps the database contents, but does no searching. If the URL field was set to unique, I would imagine that there is a method of searching against the key. Based on the functionality of scriptindex, it determines whether to the record already exists or not before updating or adding to the index. This latter functionality is the one I want to utilize because based on the nature of the datastructure and keys, searching should be very fast. I'll check the scriptindex sources to see if I can understand what's going on there.

Thanks,
-OSC
