Hey @ranjeet.tiwari. I'm confused about what you are trying to do.
Are you using facets and a "Facet" component?
If not, are you trying to build your own component that applies a filter without facets?
If so, I don't think you want to use config, you'll want to use "actions".
The general concept is documented here: https://github.com/elastic/search-ui/blob/master/ADVANCED.md#working-with-the-headless-core.
A list of actions that you have available to you are listed here: https://github.com/elastic/search-ui/blob/master/ADVANCED.md#actions.
It sounds like what you may want is the addFilter action. That will update the filters selected and trigger a new query.
