public class QueryFilterUtil
extends Object

Query Filter Utility class uses to parse filter parameters. Filter query restricts the data returned in a query request, which should take a form of http://://.social.query..?

A single filter uses the form: property operator expression where,

• property - the property name. @see MAP_INDEX_TYPE for the list of valid name.
• operator - defines the type of filter match to use.
• expression - states the values included in the results. There are couple of important rules for filter expression.
  • URL-reversed characters - Characters such as '&' must be url-encoded.
  • Reversed characters - The comma and backslash must be backslash escaped when they appear in an expression.
