NAME

Apache::Solr::Document - Apache Solr (Lucene) Document container

SYNOPSIS

  # create and upload a new document
  my $doc = Apache::Solr::Document->new(...);
  $doc->addField(id => 'tic');
  $doc->addFields( {name => 'tac', foot => 'toe'}, boost => 2);

  $solr->addDocument($doc, commit => 1, overwrite => 1)

  # take results
  my $results = $solr->select
    ( q  => 'text:gold'             # search text-fields for 'gold'
    , hl => { field => 'content' }  # highlight 'gold' in content'
    );

  my $doc = $results->selected(3);  # fourth answer
  print $doc->rank;                 # 3

  print $doc->uniqueId;             # usually the 'id' field

  @names = $doc->fieldNames;
  print $doc->field('subject')->{content};
  print $doc->content('subject');   # same
  print $doc->_subject;             # same, via autoload (mind the '_'!)

  my $hl  = $results->highlighted($doc);  # another ::Doc object
  print $hl->_content;              # highlighted field named 'content'

DESCRIPTION

This object wraps-up an document: a set of fields. Either, this is a document which has to be added to the Solr database using Apache::Solr::addDocument(), or the subset of a document as returned by Apache::Solr::select().

METHODS

Constructors

Apache::Solr::Document->fromResult(HASH, $rank)

Create a document object from data received as result of a select search.

Apache::Solr::Document->new(%options)

 -Option--Default
  boost   1.0
  fields  {}

boost => FLOAT: Boost the preference for hits in this document.
fields => HASH|ARRAY: Passed to addFields().

Accessors

$obj->addField($name, $content, %options)

$content can be specified as SCALAR (reference) for performance. In that case, a reference to the original will be kept. When "undef", the field gets ignored.

 -Option--Default
  boost   1.0
  update  undef

boost => FLOAT
update => 'add'|'set'|'inc'|...: [1.02, Solr 4.0] See 'Atomic Updates' in https://cwiki.apache.org/confluence/display/solr/Updating+Parts+of+Documents

$obj->addFields(HASH|ARRAY, %options)

The HASH or ARRAY containing NAME/CONTENT pairs. The %options are passed addField() as %options.

$obj->boost( [$fieldname, [$boost]] )

Boost value for all fields in the document.

[0.93] When a FIELD NAME is given, the boost specific for that field is returned (not looking at the document's boost value) This can also be used to set the $boost value for the field.

$obj->content($name)

Returns the content of the first field with $name.

$obj->field($name)

Returns the first field with $name (or undef). This is a HASH, containing "name", "content" and sometimes a "boost" key.

If you need the content (that's the usually the case), you can also (probably more readible) use the (autoloaded) method NAMEd after the field with a leading '_'.

example:

   $doc->field('subject')->{content};
   $doc->content('subject');
   $doc->_subject;

$obj->fieldNames()

All used unique names.

$obj->fields( [$name] )

Returns a list of HASHs, each containing at least a "name" and a "content". Each HASH will also contain a "boost" value. When a $name is provided, only those fields are returned.

$obj->rank()

Only defined when the document contains results of a search: the ranking. A value of '0' means "best".

$obj->uniqueId()

Returns the value of the unique key associated with the document "id". Only the server knowns which field is the unique one. If it differs from the usual "id", you have to set it via global value $Apache::Solr::uniqueKey
