How to search all keys inside MongoDB collection using only one keyword

Is there a way for MongoDB to search an entire collection's keys' contents using only a single search keyword?
Suppose I have the following collection (let's call it foodCollection):
{
name: "Chocolate Mousse Cake",
type: "Cake"
},
{
name: "Mother's Cookies",
type: "Cookies"
},
{
name: "Dark Bar",
type: "Chocolate"
}
I want my search to look for matches that contain "Chocolate", meaning it should return "Chocolate Mousse Cake" and "Dark Bar".
I'm trying to do this using the ff: code:
Client-side controller
// Search Products
$scope.searchProduct = function () {
$http.get('/api/products/search/' + $scope.searchKeyword).success(function(data){
console.log(data);
})
.error(function(err) {
console.log("Search error: " + err);
});
}
Express.js
app.get('/api/products/search/:param', productController.search); // Search for product
Server-side controller (I used this reference from the MongoDB docs):
// Search
module.exports.search = function(req, res) {
console.log("node search: " + req.body);
Product.find({ $or: [{productName: req.body},
{productType: req.body}]
}, function(err, results) {
res.json(results);
});
}
When I executed this, I got nothing. Am I missing something?
Any help would be greatly appreciated. Thank you.
UPDATE (FINAL)
Finally solved this thanks to Joydip's and digit's tips. Here's my solution in case somebody else gets the same problem as I did:
Client-side controller
$scope.searchProduct = function () {
if ($scope.searchKeyword == '') {
loadFromMongoDB(); // reloads original list if keyword is blank
}
else {
$http.get('/api/products/search/' + $scope.searchKeyword).success(function(data){
if (data.length === 0) {
$scope.showNoRec = true; // my flag that triggers "No record found" message in UI
}
else {
$scope.showNoRec = false;
$scope.productList = data; // passes JSON search results to UI
}
});
}
}
Express.js
app.get('/api/products/search/:keyword', productController.search); // Search for product
Mongoose schema
var mongoose = require('mongoose');
var schema = new mongoose.Schema({
productName: String,
productType: String,
productMaker: String,
productPrice: Number,
createDate: Date,
updateDate: Date
});
schema.index({productName: "text", productType: "text", productMaker: "text"});
Server-side controller
module.exports.search = function(req, res) {
Product.find({$text: {$search : req.params.keyword}}, function(err, results){
res.json(results);
})
}
Thank you everyone for your help. :)

You can try by creating an Index:
db.yourollection.createIndex({"productName":1,"productType":1})
And then by searching for the value, Example:
Product.find({$text:{$search: 'Chocolate'}},{productName:1, productType:1});

If you want to search all key, then you can use
db.foodCollection.createIndex( { name: "text", description: "text" } )
then search by
db.foodCollection.find({ $text: { $search: "choco" } })

How can I make a field in a meteor Simple Schema equal to a js variable and still let the user fill out the rest of the simple schema?

I am making a meteor web app where the user will click on a html button. Once this button is clicked, the user needs to be directed to another page with some forms generated by a meteor simple schema package. The first field in the simple schema needs to automatically be given a string value of "hello" and then the rest of the fields in the simple schema will be filled out by the user with the input fields on the page. What I am unsure about is how to get the first value automatically set to this string value. Here is some of the code I have:
The simple schema declaration:
LobbySchema = new SimpleSchema({
game: {
type: String,
label: "Game"
},
console: {
type: String,
label: "Console"
},
players: {
type: Number,
label: "Players"
},
mic: {
type: Boolean,
label: "Mic"
},
note: {
type: String,
label: "Note"
},
gamertag: {
type: String,
label: "Gamertag"
},
createdAt: {
type: Date,
label: "Created At",
autoValue: function(){
return new Date()
},
autoform: {
type: "hidden"
}
}
});
The first field there in the schema "game" needs to be given the value "hello" when the html button is clicked. Right now I can assign that value to a javascript variable using the button by having an onclick function:
function getElementText(elementID){
var elementText = "hello";
}
The button would call the getElementText function and have the elementText variable equal "hello". Now I need to assign the the first field in the simple schema to this variable value, "hello", then have it so the user can now fill out the rest of the schema with the input fields, automatically generated into the html with this code:
{{> quickForm collection="Lobby" id="insertLobbyForm" type="insert" class="newLobbyForm"}}
If you do not feel like providing the answer (maybe it happens to be more complicated than I think) then I would be very happy to receive a link to a site that might help me with this. I am also very willing to explain anything about the question if I did not explain the situation well enough above.

You can use the AutoForm hooks like this:
AutoForm.hooks({
app_create: {
before: {
method: function (doc) {
// Do whatever assignment you need to do here,
// like doc['game'] = "hello"; //then
return doc;
}
},
onSuccess: function (formType, result) {
},
onError: function (formType, error) {
}
}
});
Where here app_create is the id of the form you're sending with Autoform.

Meteor - Filter a Collection at template level subscription?

Currently I have a template which subscribes to a collection:
Template.Actividades.onCreated(function(){
var self = this;
self.autorun(function(){
self.subscribe("recursos");
});
});
Template.Actividades.helpers({
recursos: function() {
return Recursos.find({clase: "Actividades"});
}
});
unfortunately when I do the find({}) with the condition I still get all the items in the collection to display and not just the ones that have "Actividades" as the "clase".
Below is the Collection Schema relevant to this part:
RecursosSchema = new SimpleSchema({
clase: {
type: String,
label: "Clase",
allowedValues: ["Actividades", "Colegios", "Jardines"],
autoform: {
afFieldInput: {
firstOption: "(Selecciona una clase)"
}
}
},
Question is what am I doing wrong in the find({}) condition?
Thanks for the help.

Issue was fixed, the incorrect code was at the iterating template level.
Thanks for the help.

ElasticSearch Javascript, Highlight not working

we switched recently to ElasticSearch Angular version and everything is working as expected except the Highlight, which is not returned at all.
This is how I setup a demo query:
$esClient.search({
index: 'myIndex',
body: {
size: 10,
from: 0,
query: query,
highlight: {
fields: {
"_all": { "pre_tags": ["<em>"], "post_tags": ["</em>"] }
}
}
}
}).then(function (result) {
// map the resultset for Row Template
var currentRows = result.hits.hits.map(function (record) {
return {
"type": record._type,
"entity": record._source, // the result
"highlight": record.highlight, // the highlights
"id": record._id // Search record ID
};
});
});
If I use the same code with a classic XmlHttpRequest and pass the query model inlcuding the highlight, I get back a JSON which contains an highlight array per each result, while using the ElasticSearch Angular client the query succeed but I don't get back the highlight.
Am I doing something wrong?

I think you might want to change to this format:
{
"query" : {...},
"highlight" : {
"pre_tags" : ["<tag1>"],
"post_tags" : ["</tag1>"],
"fields" : {
"_all" : {}
}
}}

How to add a new object to an array nested inside an object?

I'm trying to get a handle on using $resource in angularjs and I keep referencing this answer AngularJS $resource RESTful example for good examples. Fetching a record and creating a record work fine, but now i'm trying to add a "section" to an existing mongo record but can't figure it out.
documents collection
{
_id: 'theid',
name: 'My name",
sections: [
{
title: 'First title'
},
{
title: 'Second title'
}
]
}
angular controller snippet
var document = documentService.get({_id: 'theid'});
// TRYING TO ADD $scope.section TO THE SECTIONS ARRAY IN THE VARIABLE document.
//document.sections.push($scope.section); <-- This does NOT work
//document.new_section($scope.section); <-- could do this and then parse it out and insert it in my backend code, but this solution seems hacky and terrible to me.
document.$save(function(section) {
//$scope.document.push(section);
});
documentService
return $resource(SETTINGS.base + '/documents/:id', { id: '#id' },
{
update: { method: 'PUT' }
});
From the link i posted above, If I was just updating the name field, I could just do something like this:
var document = documentService.get({_id: 'theid'});
document.name = "My new name";
document.$save(function(section) {
//$scope.document.push(section);
});
I'm just trying to add an object to a nested array of objects.

Try this:
documentService.get({_id: 'theid'}, function(document) {
document.sections.push($scope.section);
document.$save();
});
