[Xapian-discuss] Long query times

[tech at dbx.co.uk]

Thanks for that Olly,

I must be being thick here -but how do I set the weighting scheme to
Boolean only though?
The Weight classes aren't implemented in Perl.

Cheers,

Jeremy

It's the latter - set_docid_order replaces set_sort_forward.  It was rather
poorly named before, and people tended to think it controlled the order
when sorting on a value (which wasn't possible before).

Old "true" is new ASCENDING, while "false" is DESCENDING.  DONT_CARE is
new in the new interface (conceptually it allows the matcher and backend
to pick whichever order is most efficient to use but currently it always
results in ASCENDING).

Hmm, looking at the docs I realise that as well as saying they're for
compatibility, we should point users at the replacement methods!  I'll
fix that...

Cheers,
    Olly
