Unable to search inner-substings ...

Hi All:

http://docs.webix.com/samples/02_toolbar/13_search_field.html

This code can search to first starting letters, but not substrings within the title. For example, search to ‘the bad’ or ‘the ugly’?
How can I modify the code to get search to find inner-substrings?

Thank you

You can define a custom filtering function, in above case just change few last lines

	$$("dview").filter(function(obj){ 
		return obj.title.toLowerCase().indexOf(value) != -1;
	})
