Yes, look, I create a class name "Lucene" who is extended to
Zend_Search_Lucene, so this is the action where I try to make the "find", it's
not done yet, but thes is the base code:
public function searchAction()
{
// Load Lucene lib.
$objLucene = new Lucene( LUCENE_INDEX_PATH );
// Open Lucene index file and get the Lucene Proxy object from the return.
$objLuceneIndex = $objLucene->open( LUCENE_INDEX_PATH );
// Try to find this text in the Lucene index file.
$objLuceneQueryHits = $objLuceneIndex->find( $this->getRequest()->getPost(
'text' ) );
// Loop hits and create a common structure to show this data into the view.
foreach ( $objLuceneQueryHits AS $objLuceneHit )
{
// Get Lucene Document object to retrieve data.
$objLuceneDocument = $objLuceneHit->getDocument();
echo "url: " . $objLuceneDocument->getField( 'url' ) . " -- " .
$objLuceneDocument->getFieldValue( 'url' );
echo "identifier: " . $objLuceneDocument->getField( 'identifier' ) . "
-- " . $objLuceneDocument->getFieldValue( 'identifier' );
echo "title: " . $objLuceneDocument->getField( 'title' ) . " -- " .
$objLuceneDocument->getFieldValue( 'title' );
echo "content: " . $objLuceneDocument->getField( 'content' ) . " -- " .
$objLuceneDocument->getFieldValue( 'content' ) . "<hr>";
}
exit();
}
And when I'm adding content to the index I'm just doing like the ZFW manual
example, but I create a method in my "Lucene" class to set a field with his
content as a php switch:
/**
* Function to set content into Lucene index.
*
* @param string $strName Name of the current element to be indexed.
* @param string $strContent Content to be indexed by Lucene.
* @param string $strType Lucene field types, text, keyword, unstored.
* @return void
*
* NOTE: More info at
http://framework.zend.com/manual/en/zend.search.lucene.html.
*/
public function setLuceneContent( $strName, $strContent, $strType = "text" )
{
// Try to open the Lucene index file.
try
{
// Load Lucene index file.
$objLuceneProxy = self::open( LUCENE_INDEX_PATH );
}
catch ( Exception $objError )
{
throw new Exception( "Can't open the Lucene index file
({$objError->getMessage()})" );
}
// Get Lucene index document.
$objLuceneDocument = new Zend_Search_Lucene_Document();
// Validate if we really have something to be indexed by Lucene.
if ( false !== empty( $strContent ) )
{
throw new Exception( "Content to be indexed by Lucene can't be empty." );
}
// If the name is empty, ergggghhh.... ERROR!
if ( false !== empty( $strName ) )
{
throw new Exception( "There's not name for the current element to be
indexed." );
}
// Start indexed using a Lucene field type.
switch ( $strType )
{
case "text":
// Add "Text" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::Text( $strName,
htmlentities( strip_tags( $strContent ) ) ) );
break;
case "keyword":
// Add "Keyword" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::Keyword( $strName,
htmlentities( strip_tags( $strContent ) ) ) );
break;
case "unstored":
// Add "UnStored" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::UnStored( $strName,
htmlentities( strip_tags( $strContent ) ) ) );
break;
case "binary":
// Add "UnStored" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::Binary( $strName,
htmlentities( strip_tags( $strContent ) ) ) );
break;
case "unindexed":
// Add "UnStored" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::UnIndexed(
$strName, htmlentities( strip_tags( $strContent ) ) ) );
break;
default:
// Add "Text" field to the Lucene index content.
$objLuceneDocument->addField( Zend_Search_Lucene_Field::Text( $strName,
htmlentities( strip_tags( $strContent ) ) ) );
break;
}
// Try to add fields to the current Lucene document.
try
{
// Add current Lucene field to the Lucebe Document.
$objLuceneProxy->addDocument( $objLuceneDocument );
}
catch ( Exception $objError )
{
throw new Exception( "Can't add this field ({$strType}) to the Lucene index
file ({$objError->getMessage()})" );
}
}
So when I want to add data to the Lucene index I just make:
// Try to set the identifier and the page url into Lucene.
try
{
// Set page title as text.
Lucene::setLuceneContent( 'url', PAGE_QUERY_STRING .
"/{$arrPageData['page']['identifier']}" );
// Set page identifier as a keyword.
Lucene::setLuceneContent( 'identifier', $arrPageData['page']['identifier'],
'keyword' );
}
catch ( Exception $objError )
{
throw new Exception( "Can't index this content ({$objError->getMessage()})"
);
}
I really dont know what's the problem, thx for any help.

Hi Juan,
Could you give an example of your code?
With best regards,
Alexander Veremyev.

:)
Im trying to retrieve data from my index, but when I try to do an echo from one
of the hits I always get that the field is not found in the document, in my
case I'm adding four fields, url -> text, identifier -> keyword, content ->
unstored and title -> text, but when I print the hits object I see that the
fields are there:
...
[_fields:private] => Array
(
[0] =>
Zend_Search_Lucene_Index_FieldInfo Object
(
[name] => url
[isIndexed] => 1
[number] => 0
[storeTermVector]
=> 0
)
[1] =>
Zend_Search_Lucene_Index_FieldInfo Object
(
[name] => identifier
[isIndexed] => 1
[number] => 1
[storeTermVector]
=> 0
)
[2] =>
Zend_Search_Lucene_Index_FieldInfo Object
(
[name] => content
[isIndexed] => 1
[number] => 2
[storeTermVector]
=> 0
)
[3] =>
Zend_Search_Lucene_Index_FieldInfo Object
(
[name] => title
[isIndexed] => 1
[number] => 3
[storeTermVector]
=> 0
)
)
...
This is waht I got in the folder where I'm storing the Lucene index:
-rw-r--r-- 1 www-data www-data 670 Jul 30 20:56 _d.cfs
-rw-r--r-- 1 www-data www-data 107 Jul 30 20:56 _d.sti
-rw-r--r-- 1 www-data www-data 4 Jul 30 20:44 deletable
-rw-r--r-- 1 www-data www-data 0 Jul 30 20:58 index.lock
-rw-r--r-- 1 www-data www-data 0 Jul 30 20:56 index.optimization.lock
-rw-r--r-- 1 www-data www-data 27 Jul 30 20:56 segments
Any help ?
