redis-index v4.1.0

redis-index

Index and query arbitrary objects with Redis.

example

var index = require('redis-index').createIndex('item', 'item_id');

index.add({ item_id : 1, name : "thing a", type : 100 });
index.add({ item_id : 2, name : "thing b", type : 100 });
index.add({ item_id : 3, name : "thing c", type : 200 });

setTimeout(function () {
	index.search({ name : 'b' }).or({ item_id : 1 }).exec(function (err, result) {
		/*
			[ { item_id : 1, name : "thing a", type : 100 },
			{ item_id : 2, name : "thing b", type : 100 } ]
		*/
	});
}, 1000);

api

RedisIndex

• RedisIndex.createIndex(options)

Create a new index to which objects may be added.

• options : options objects key : string - the namespace key to use when storing keys in redis index : string - the attribute which exists on an object being indexed which should be used to uniquely identify that object. schemaOnly : boolean - when true, only index fields identified in the schema fullText : function - when exists, this function will be called with each object being added to the index. The function should return a string to be indexed for full text search. This option must be present in order to enable full text search. schema : object - an object which identifies information about attributes encountered when indexing. compress : object - and object with synchronous encode and decode functions for compressing and decompressing values

more examples

compression

var RedisIndex = require('redis-index');

var index = RedisIndex.createIndex({
	key : 'item'
	, index : 'item_id'
	, compress : RedisIndex.compression.gzip
});

TODO

• proper tests
• comparisons
• deep lookups
• arrays of values
• arrays of objects
• automatic full deep indexing
• wildcards for schema definitions
• add comparisons - exists - empty/notExists - contains - begins with - ends with - x in array (of values)
• full text
• string comparisons
• sorting
• intersect with other indexes
• store key
• add array of objects
• custom string tokenizing
• paging
• make Promise compatible
• compression
