2-ReadWriteDocument.php

<?php

// make Solarium available
require('Solarium/Autoloader.php');
Solarium_Autoloader::register();

// create a client instance
$client = new Solarium_Client;
$client->setHost('192.168.1.2');
$client->setPort(8983);
$client->setPath('/solr/');
$client->setCore('geonames');

// create a new document
$document = new Solarium_Document_ReadWrite;

// set a field value as property
$document->id = 15;

// set a field value as array entry
$document['population'] = 120000;

// set a field value with the setField method, including a boost
$document->setField('name', 'example doc', 3);

// add two values to a multivalue field
$document->addField('countries', 'NL');
$document->addField('countries', 'UK');

// set a field to multiple values, this overwrites any existing (multi)value for this field!
$document->countries = array('DE','FR','IT');

// example: add / remove field with methods
$document->setField('dummy', 10);
$document->removeField('dummy');

// example: add / remove field with methods by setting NULL value
$document->setField('dummy', 10);
$document->setField('dummy', NULL); //this removes the field

// example: add / remove field as object property
$document->dummy = 10;
unset($document->dummy);

// example: add / remove field as array entry
$document['dummy'] = 10;
unset($document['dummy']);

// set a document boost value
$document->setBoost(2.5);

// set a field boost
$document->setFieldBoost('population', 4.5);

// add it to the update query and also add a commit
$query = new Solarium_Query_Update;
$query->addDocument($document);
$query->addCommit();

// run it, the result should be a new document in the Solr index
$client->update($query);
