Mongodb Nodejs Regex Search - node.js

Question

Hey I am making a website which as a partial search form. Reference from:https://www.youtube.com/watch?v=ZC2aRON3fWw&t=42s But I couldnt understand why it doesnt work. I use pug instead of hbs.
And these are my codes:
app.get('/sonuc', function(req, res, next){
var q = req.query.q;
Article.find({
title : {
$regex: new RegExp(q)
}
}, {
_id:0,
__v:0
}, function(err, data){
res.render('sonuc', {data:data})
}).limit(10);
});
});
Then this is my layout pug:
.ui-widget
form.form-inline.my-2.my-lg-0
input.form-control.mr-sm-2(type='text', onkeyup='showResults(this.value)', placeholder='Search',action='/article/'+sorgu, aria-label='Search')
button.btn.btn-secondary.my-2.my-sm-0(type='submit')
#search-results(style='width:60px;top:-1px;position:relative')
In this layout pug I thing the onkeyup issue is not working. How can I implement that fu nction on that form?
And ths is my main.js whihc takes query from database and write it in html form:
var showResults = debounce(function(arg){
var value = arg.trim();
if(value == "" || value.length <= o){
$("#search-results").fadOut();
return;
}else{
$("#search-results").fadeIn();
};
var jqhr = $.get('/article/' + value, function(data){
})
.done(function(data){
if(data.length == 0){
$("search-resuts").append('<p classs="lead text-center mt-2">No Results</p>');
}else{
data.forEach(x => {
$("search-resuts").append('<p class="m-2 lead"><img style="width:60px;" src="images/supreme1.jpg">' + x.title +'</p>');
});
}
})
.fail(function(err){
console.log(err);
})
}); 200;
function debounce(func, wait, immediate){
var timeout;
return function(){
var context = this;
args = arguments;
var later = function(){
timeout= null;
if(!immediate)func.apply(context,args);
};
var callNow = immediate && !timeout;
clearTimeout(timeout);
timeout = setTimeout(later, wait);
if(callNow)func.apply(context,args);
};
};
I cannot understand these issues and why it doesnt work.As a summary, I want to make a search engine which works with regex and mongodb. İt will be partial that is shown in that youtoube video which is on the above of my article that I referenced. But the real issue is, I couldnt understand the code block of function showResults and I dont know how to translate this codes to my project. So that I am waiting your help. I cannot upload a video to this website so that if you can give me your facebook, instagram or email account I can send the issue which should be solved. I need your help. I have been making this project for a long time for my school but I cannot move on. Please I need your help.
I hope I could express myself well and your helps will solve it.

Answer 1

Yes I got it know. I have made lots of changes instead of using this code blockes.
I wathced : https://www.youtube.com/watch?v=9_lKMTXVk64
And also I documented : Fuzzy Searching with Mongodb?
These two documentations help me a lot. So that my code is almost approximately 90% same as shown in these documentations.
This is my app.js :
app.get('/sonuc', function(req, res){
if (req.query.search) {
const regex = new RegExp(escapeRegex(req.query.search), 'gi');
Article.find({ "title": regex }, function(err, articles) {
if(err) {
console.log(err);
} else {
res.render("index", {
articles: articles
});
}
});
}
});
This is my index.pug file :
extends layout
block content
body
br
br
br
ul.list-group
each article, i in articles
li.list-group-item
a(href="/article/" + article._id)= article.title
And this is my layout.pug file(But I will consider the text form)
form.form-inline.my-2.my-lg-0(action="/sonuc" method="GET")
input.form-control.mr-sm-2(type='text', name,="search", onkeyup='showResults(this.value)', placeholder='Search',action='/article/'+sorgu, aria-label='Search')
button.btn.btn-secondary.my-2.my-sm-0(type='submit')
Please look at:
https://github.com/nax3t/fuzzy-search
Because in my solution I didnt add the message that is applied when we cannot find the word. Or when there is no such a word which is searched by user. The noMatch query.
But after I will apply it to my project I will add it to here.
