<br>
try the following:<br>
<br>
featureStore.proxy.setFilter(your_new_filter);<br>
featureStore.reload();<br>
<br>
But note that you could also configure your vector layer with your protocol and a BBOX strategy, and bind your featureStore to that layer by configuring the store's layer property. This will make the BBOX strategy take care of requesting features for the correct extent.<br>
<br>

Andreas.<br>
