valueBool flag
Example #1 SolrQuery::setExpand() example
<?php
$query = new SolrQuery('lucene');
$query
->setExpand(true)
->setExpandRows(50)
->setExpandQuery('text:product')
->addExpandFilterQuery('manu:apple')
->addExpandFilterQuery('inStock:true')
->addExpandSortField('score', SolrQuery::ORDER_DESC)
->addExpandSortField('title', SolrQuery::ORDER_ASC);
echo $query.PHP_EOL;
?>
以上例程的输出类似于：
q=lucene&expand=true&expand.rows=50&expand.q=text:product&expand.fq=manu:apple&expand.fq=inStock:true&expand.sort=score desc,title asc
