Example #1 SolrDisMaxQuery::removeBoostQuery() example

`<?php
$dismaxQuery = new SolrDisMaxQuery("lucene");
$dismaxQuery
->addBoostQuery('cat', 'electronics', 5.1)
->addBoostQuery('cat', 'hard drive')
;
echo $dismaxQuery.PHP_EOL;
// now remove a query part with field 'cat'
$dismaxQuery
->removeBoostQuery('cat');
echo $dismaxQuery . PHP_EOL;
?>`
