 * 
 * This is the search engine based on dinamic grouping of objects in more than one sets.
 * Example: 
 * 		you can have from 1 to N main groups
 * 		for each group you can have 1 to X categories
 * 		for each category you can have 1 to Y contents
 * 		Each content can be present in 1 or more categories at a time
 * 
 * 		Real world example based on ancient objects:
 * 			Groups and categories: 
 * 				- MATERIAL
 * 					- Metal
 * 					- Wood
 * 					- Glass
 * 					- Pottery
 * 				- ROOM
 * 					- Bedroom
 * 					- Bathroom
 * 					- Kitchen
 * 					- Salon
 * 				- AGE
 * 					- 700
 * 					- 800
 * 					- 900
 * 
 * A LAVATORY can be placed in
 * 		Material: Pottery, 
 * 		Room : Bathroom,
 * 		Age : 800
 * 
 * An OIL LAMP can be placed in
 * 		Material: Metal, Glass
 * 		Room: Bedroom, Kitche, Salon
 * 		AGE: 700,800,900
 * 
 * Algorithm:
 * 
 * 	1) Get Groups and categories from server, the initial request can be something like this:
  		request: {
  			Action: 'getgroups'
  		}
  		response: {
  			Groups:[
  				{groupname: 'MATERIAL'},
  				{groupname: 'ROOM'},
  				{groupname: 'AGE'}
  			]
  		}
 * 	2) Compose a graphic interface tool to let the user compose his query selecting 
 * 	   with a flag each category of items included in the result, for each click
 * 	   on the flag near the category the client JS asks to PHP the resulting combination of other groups categories 
 * 	   for the objects composing the resultset, the resultset is displayed in a resulting table with result pagination
 * 	   if result are more than N
 
		request:{
  			Groups:[
  				{
  					groupname: 'MATERIAL',
  					categories:[
  						{categoryname:'Metal'}
  					] 
  				},
  				{
  					groupname: 'ROOM',
  					categories:[
  						{categoryname:'Bedroom'},
  						{categoryname:'Salon'}
  					] 
  				},
  				 				{
  					groupname: 'AGE',
  					categories:[
  						{categoryname:'700'}
  					] 
  				}
  			]
		} 
		
		response:{
			contents:[
				{
					RecId: '09832083290',
					cTitle: 'OIL LAMP',
					cIntroText: 'The real 700 Oil lamp of Mr. Ciccio',
					....
				} 
			]
		}
