title: Chain Search Query Helpers to Narrow Search Results
challengeType: 2
---
## Description
If you don’t pass the callback as the last argument to Model.find()
(or to the other search methods), the query is not executed. You can store the query in a variable for later use. This kind of object enables you to build up a query using chaining syntax. The actual db search is executed when you finally chain the method .exec()
. You always need to pass your callback to this last method. There are many query helpers, here we’ll use the most ‘famous’ ones.
## Instructions
Find people who like burrito
. Sort them by name, limit the results to two documents, and hide their age. Chain .find()
, .sort()
, .limit()
, .select()
, and then .exec()
. Pass the done(err, data)
callback to exec()
.
## Tests
```yml
tests:
- text: Chaining query helpers should succeed
testString: 'getUserInput => $.ajax({url: getUserInput(''url'') + ''/_api/query-tools'', type: ''POST'', contentType:''application/json'', data: JSON.stringify([{name: ''Pablo'', age: 26, favoriteFoods: [''burrito'', ''hot-dog'']}, {name: ''Bob'', age: 23, favoriteFoods: [''pizza'', ''nachos'']}, {name: ''Ashley'', age: 32, favoriteFoods: [''steak'', ''burrito'']}, {name: ''Mario'', age: 51, favoriteFoods: [''burrito'', ''prosciutto'']} ]) }).then(data => { assert.isArray(data, ''the response should be an Array''); assert.equal(data.length, 2, ''the data array length is not what expected''); assert.notProperty(data[0], ''age'', ''The returned first item has too many properties''); assert.equal(data[0].name, ''Ashley'', ''The returned first item name is not what expected''); assert.notProperty(data[1], ''age'', ''The returned second item has too many properties''); assert.equal(data[1].name, ''Mario'', ''The returned second item name is not what expected'');}, xhr => { throw new Error(xhr.responseText); })'
