Find records in a Extjs Store for which displayValue starts with a specific substring

I am trying to fetch records from ExtJS store which start with specific substring.

e.g. If I have a country store and if I have a string 'IN' then I want records of India and Indonesia from store.

Is there any way to do this?

Thanks

I suppose this is about a combobox, so that's the default behavior.

If you just want to filter a store, look at:

• filters config - Array of Filters for this store.

• filter method - Filters the data in the Store by one or more fields.

• filterBy method - Filters by a function.
• Ext.util.Filter - Represents a filter that can be applied to a MixedCollection.
