note 117836 added to mongocursor.hint

For the series we’ll assume we have a collection named posts populated with 500 documents having the following structure: { "_id": ObjectId("5146bb52d852470060001f4"), "comments": { "0": "This is the first comment", "1": "This is the second comment" }, "post_likes": 40, "post_tags": { "0": "MongoDB", "1": "Tutorial", "2": "Indexing" }, "post_text": "Hello Readers!! This is my post text", "post_type": "private", "user_name": "Mark Anthony" } The hint() method can be used to force MongoDB to use an index we specify and override the default selection and query optimization process. You can specify the field names used in the index as a argument as shown below: <?php // query to find posts with type public and 100 likes // use hint() to force MongoDB to use the index we created $cursor = $collection ->find( array( "post_type" => "public", "post_likes" => 100 ) ) ->hint( array( "post_type" => 1, "post_likes" => 1 ) ); ?> This ensures the query uses the compound index defined on the post_type and post_likes fields. ---- Server IP: 72.52.91.14 Probable Submitter: 202.88.246.140 ---- Manual Page -- http://php.net/manual/en/mongocursor.hint.php Edit -- https://master.php.net/note/edit/117836 Del: integrated -- https://master.php.net/note/delete/117836/integrated Del: useless -- https://master.php.net/note/delete/117836/useless Del: bad code -- https://master.php.net/note/delete/117836/bad+code Del: spam -- https://master.php.net/note/delete/117836/spam Del: non-english -- https://master.php.net/note/delete/117836/non-english Del: in docs -- https://master.php.net/note/delete/117836/in+docs Del: other reasons-- https://master.php.net/note/delete/117836 Reject -- https://master.php.net/note/reject/117836 Search -- https://master.php.net/manage/user-notes.php
