Re: [fw-general] get all index terms in Zend Lucene

[meecect]

This works (defined in segmentInfo.php):

    public function getTerms()
    {
        $result=array();

        $tisFile = $this->openCompoundFile('.tis');
        $tiVersion = $tisFile->readInt();
        if ($tiVersion != (int)0xFFFFFFFE) {
            throw new Zend_Search_Lucene_Exception('Wrong TermInfoFile file
format');
        }

        $termCount     = $tisFile->readLong();
        $indexInterval = $tisFile->readInt();
        $skipInterval  = $tisFile->readInt();
        $prevTerm     = '';
        $freqPointer  =  0;
        $proxPointer  =  0;
        $indexPointer =  0;
        for ($count = 0; $count < $termCount; $count++) {
            $termPrefixLength = $tisFile->readVInt();
            $termSuffix       = $tisFile->readString();
                        $termFieldNum           = $tisFile->readVInt();
            $termValue        = substr( $prevTerm, 0, $termPrefixLength ) .
$termSuffix;                    
            $docFreq      = $tisFile->readVInt();
            $freqPointer += $tisFile->readVInt();
            $proxPointer += $tisFile->readVInt();
            if( $docFreq >= $skipInterval ) {
                $skipOffset = $tisFile->readVInt();
            } else {
                $skipOffset = 0;
            }
            $result[] =  array($termValue);
            $prevTerm = $termValue;
        }
        return $result;
    }
