Steve,
I have used the first solution, and it does work using $map->draw() and
in rgba mode. Here is my code that uses filter.
if (isset($key_counties) && !empty($key_counties)){
$filter = "(ogc_fid = {$key_counties[0]})";
for($i=1; $i<count($key_counties); $i++){
$filter .= " or (ogc_fid = {$key_counties[$i]})";
}
$this_layer = $map->getLayerByName('counties_q');
$this_layer->setFilter($filter);
$this_layer->set('status', MS_ON);
}
Thanks a lot for the assistance.

How many search results are you seeing on average? There are a couple
of
work arounds:
1 - one would be to use the result set to craft a filter for the
layer(s) in question
so that only those features that match the filter get drawn
2 - another would be to add the features to the layer or a copy of the
layer (e.g.
use inline features instead of the datasource)
In both cases you'd use $map->draw() instead of drawQuery() and would
avoid
the alpha blending problem. Option one would work nicely if you have
relatively
few (less than 20) features, while the other would work well in any
case.
