elasticsearch - Wrong count for nested facets -


i'm building search products , variants. 1 product can have many nested variants. example: 1 t-shirt can in 2 variants, white 50 euros , green 60 euros. it's still same product , should displayed once on results page.

this mapping:

{"product" => { "properties" => {"vendor_variants" => {"type" => "nested"}}}}

and query i'm doing:

"query" => {     "filtered" => {       "query" => {         "match_all" => {}       },       "filter" => {         "bool" => {           "must" => [             {               "terms" => {                 "categories" => [122]               }             }           ]         }       }     }   },   "facets" => {     "brand" => { "terms" => {"field" => "filter_brand"} },     "price_range" => {       "nested" => "vendor_variants",       "range" => { "field" => "price", "ranges" => [ {"to" => 2000}, {"from" => 2000, "to" => 5000} ]       }     }   }

this query produces 172 results. facets price ranges wrong. example returns 20-50 euro range there 422 results. believe it's because counts every single nested vendor_variants document. it's not need, need count main product documents.

what wrong query?

figured out. in mapping nested document, had add "include_in_parent" => true

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
