NAME
KinoSearch::Plan::Schema - User-created specification for an inverted index.
DEPRECATED
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
SYNOPSIS
use KinoSearch::Plan::Schema;
use KinoSearch::Plan::FullTextType;
use KinoSearch::Analysis::PolyAnalyzer;
my $schema = KinoSearch::Plan::Schema->new;
my $polyanalyzer = KinoSearch::Analysis::PolyAnalyzer->new(
language => 'en',
);
my $type = KinoSearch::Plan::FullTextType->new(
analyzer => $polyanalyzer,
);
$schema->spec_field( name => 'title', type => $type );
$schema->spec_field( name => 'content', type => $type );DESCRIPTION
A Schema is a specification which indicates how other entities should interpret the raw data in an inverted index and interact with it.
Once an actual index has been created using a particular Schema, existing field definitions may not be changed. However, it is possible to add new fields during subsequent indexing sessions.
CONSTRUCTORS
new()
my $schema = KinoSearch::Plan::Schema->new;Constructor. Takes no arguments.
METHODS
spec_field( [labeled params] )
Define the behavior of a field by associating it with a FieldType.
If this method has already been called for the supplied field, it will merely test to verify that the supplied FieldType equals() the existing one.
name - The name of the field.
type - A FieldType.
num_fields()
Return the number of fields currently defined.
all_fields()
Return all the Schema's field names as an array.
fetch_type(field)
Return the FieldType for the specified field. If the field can't be found, return undef.
fetch_sim(field)
Return the Similarity for the specified field, or undef if either the field can't be found or it isn't associated with a Similarity.
architecture()
Factory method which creates an Architecture object for this index.
get_architecture()
Return the Schema instance's internal Architecture object.
get_similarity()
Return the Schema instance's internal Similarity object.
INHERITANCE
KinoSearch::Plan::Schema isa KinoSearch::Object::Obj.
