NAME ^

SWISH::Prog::Xapian::Searcher - Swish3 Xapian backend Searcher

SYNOPSIS ^

 # see SWISH::Prog::Searcher

DESCRIPTION ^

SWISH::Prog::Xapian::Searcher is not made to replace the more fully-featured Search::Xapian. Instead, SWISH::Prog::Xapian::Searcher provides a simple API similar to other SWISH::Prog::Searcher-based backends so that you can experiment with alternate storage engines without needing to change much code. When your search application requirements become more complex, the author recommends the switch to using Search::Xapian directly.

METHODS ^

Only new and overridden methods are documented here. See the SWISH::Prog::Searcher documentation.

init( params )

Overrides superclass to build map of PropertyNames to ids, since Xapian stores values by id not name.

prop_id_map

Get the read-only internal map for PropertyNames to id values.

search( query [, opts ] )

Returns a SWISH::Prog::Xapian::Results object.

opts is an optional hashref with the following supported key/values:

start

The starting position. Default is 0.

max

The ending position. Default is max_hits().

order

The sort order. Default is by score. This feature is not yet supported.

get_facets

If set to an array ref of field names, then the Results object will contain a hash ref of facet counts for those fields.

facet_sample

How many results to examine when counting facets. Default is all of them.
