Search::GIN::Query::Set - Create queries with set operations VERSION
version 0.08 SYNOPSIS
# build a query like: # (type:pdf OR type:png) AND (name:Homer OR name:Bart) use Search::GIN::Query::Set; use Search::GIN::Query::Manual; my $query = Search::GIN::Query::Set->new( operation => 'INTERSECT', subqueries => [ Search::GIN::Query::Manual->new( values => { type => [qw(pdf png)] } ), Search::GIN::Query::Manual->new( values => { name => [qw(Homer Bart)] } ), ] ); DESCRIPTION
Creates a manual GIN query that can be used to search using basic set theory, in order to build more complex queries. This query doesn't provide any specific search, it's just a set operator for subqueries. You can build complex queries by using other set queries as subqueries for a set query. METHODS
/SUBROUTINES new Creates a new query. ATTRIBUTES
subqueries The subqueries to process operation One of the basic set operators: "UNION", "INTERSECT" and "EXCEPT". The default is "UNION" AUTHOR
