add an option to specify whether filter terms of a given prefix should be ORed or ANDed together

[tv+xapian.org]

Hi,

the patch at http://people.debian.org/~tviehmann/list-search/xapian_omega_add_option_filter_defaultop.diff adds an option map to allow overriding the filter behaviour from OR to AND among the terms of a given prefix. For example, if first and last name are indexed with prefix A, I would add

$setmap{filter_defaultop,A,AND}

to the query template in order to be handle first, last, or first and last name entered into the appropriate fields.

Kind regards

Thomas

I tend to feel that this particular case would be better handled by allowing Omega to parse the author field probabilistically - the current approach comes from a nasty hack I used for Gmane I believe.

But there might be uses for AND rather than OR on the same prefix, so the patch might still be worthwhile. It would need to be a case where the filter terms are overlapping but not just in a subset/superset way.
