KinoSearch::Plan::ScheUser)Contributed Perl DocumenKinoSearch::Plan::Schema(3)NAMEKinoSearch::Plan::Schema - User-created specification for an inverted
index.
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.
CONSTRUCTORSnew()
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.
