[OpenLayers-Users] Filtering a vector Layer

[Aparna]

Finally, was able to filter the vector layer,. The biggest problem was to
use multiple values and/or multiple filter options and could not create
permulation combination of OGC filters(logical, comparison, ..). This
seemed rather difficult at first. Eventually created CQL filters
which were converted. This is the layer

var state = new OpenLayers.Layer.Vector("Karnataka", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                filter:"",
                protocol: new OpenLayers.Protocol.WFS({
                    version: "1.1.0",
                    url: "http://localhost:8085/geoserver/wfs",

                    featureType: "karf",
                    featureNS: "http://opengeo.org/India"

                }),


            });

and then logical OR or Logical AND was wrapped with comparison Filters and
converted to OGC.
