<?php
$dismaxQuery = new SolrDisMaxQuery("lucene");
$dismaxQuery
->addQueryField("location", 4)
->addQueryField("price")
->addQueryField("sku")
->addQueryField("title",3.4)
;
echo $dismaxQuery;
?>
The above example will output
something similar to:
q=lucene&defType=edismax&qf=location^4 price sku title^3.4
