How to filter feature using openlayer and WFS?
But I’m facing problem when I only want to display the data with certain features aka filtering. I followed filtering tutorial from https://www.giserdqy.com/wp-content/guids/ol-v4.6.5/examples/vector-wfs-getfeature.html and I also have tried using CQL_FILTER but no luck at all
What are the parameters for the WFS reader?

Do you need privileges to publish hosted WFS layers?
Hosted WFS layers must be shared with everyone to draw correctly. Publish a hosted feature layer of the data you need. You must have privileges to create content and publish hosted feature layers. If you are not already signed in to ArcGIS Online, do so now.
Is the hosted OGC feature dependent on the hosted WFS layer?
The hosted OGC feature or WFS layer is dependent on the hosted feature layer. You can also publish a hosted OGC feature or WFS layer from a hosted feature layer view. When you do, any view definition set on the view is preserved in the dependent layer. Hosted OGC feature and WFS layers are read-only.
How are feature layers similar to hosted feature layers?

How does layer 2 filtering work in Windows 10?
This WFP feature allows filtering on fields of the layer 2 MAC header. These layers are invoked on a per-packet basis for all packets that are sent or received by the host machine. The layers are invoked prior to packet reassembly on the inbound path and after packet fragmentation on the outbound path.
How are layers invoked in NDIS LightWeight Filter driver?
The layers are invoked prior to packet reassembly on the inbound path and after packet fragmentation on the outbound path. These layers are accessed from an NDIS lightweight filter (LWF) driver. A callout should not inject packets at a layer if it does not already have a corresponding filter at that layer.
When to inject packets into a filter layer?
A callout should not inject packets at a layer if it does not already have a corresponding filter at that layer. The injection of the NET_BUFFER_LIST structures should be coordinated with the filter addition and removal so that injection is only performed when the filter exists in the corresponding layer.
