createIndexes() – Creates one or more indexes on a collection

indexes

keyPatterns : An array containing index specification documents.

• Each document contains field and value pairs, where the field is the index key and the value describes the type of index for that field.
• Syntax:

  {<index key> : -1|1}

  where 1 specifies an index in ascending order and -1 specifies an index in descending order.

.

The following example shows the command syntax for creating a series of indexes for the collection, members:

db.members.createIndexes([ { score : 1 }, { price : 1 }, { task : 1 }, { category : 1 } ])

The following example shows the output returned from running the createIndexes command:

{
    “indexName1” : “members_xscore”,
    “indexName2” : “members_xprice”,
    “indexName3” : “members_xtask”,
    “indexName4” : “members_xcategory”
}
