You are looking at this line without the context. There is also:
if(options.single == true) {
this.selectBestFeature(result.features,
bounds.getCenterLonLat(), options);
} else {
this.select(result.features);
}
One of the key advantages of the GetFeature control over WMSGetFeature
is that it will *always* just return *one single feature* on a click,
and this feature will be the *best matching one*. The maxFeatures config
option is just about how many features to use to determine the best
matching one. Maybe this should be documented better.
