Mongoose partial text search with sorting by revelance

I'm trying to query my mongodb database via mongoose, sorting the most relevant items first.
The following code works, but only returns results that contain the search parameter as a full word.
E.g. example will return items that include fields such as, ⁣ but{name: "example-item", description: "this is an example description"} but examp won't return that same item. I'd also like for it to search across multiple fields, as my current code does.
I'm aware you can do this partial search using regex but then you're not able to sort by textScore. Is there any way to do both? Sorting after each request is not possible as it will be paginated and handling somewhat large data.
let searchValue = "examp";
let matchingItems = await Items.find(
{
$text: {
$search: searchValue,
}
},
{
score: {
$meta: "textScore"
}
},
{
sort: {
score: {
$meta: "textScore"
}
}
}
);
Example DB data:
[
{name: "dignissim", description: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."},
{name: "Fusce eget.", description: "Nullam malesuada ex sit amet diam ultrices"},
{name: "Duis nec", description: "Proin at dolor at est porta aliquet. Proin viverra imperdiet orci, a ornare tortor"},
{name: "Mauris.", description: "Aenean tristique ante et eros porttitor, ut sodales ipsum pulvinar."},
{name: "Pellentesque", description: "Nam dignissim ipsum a elit fermentum"},
{name: "facilisis augue", description: "Etiam sit amet dolor sed sapien rutrum sodales."},
{name: "erat suscipit", description: "this is an example description"},
]
My schema is defined as below:
const mongoose = require("mongoose");
const schema = new mongoose.Schema({
name: String,
description: String
});
schema.index({ name: "text", description: "text" });
const Items = mongoose.model("Item", schema);

filter data on multiple fields

I am trying to build a filter for JSON object at the moment, the json object looks like this,
created_at: null
deleted_at: null
id: 3
listings: Array(3)
0: {id: 3, name: "Learn the basics of the guitar from the anatomy of the guitar to scales, chords", slug: "learn-the-basics-of-the-guitar-from-the-anatomy-of-the-guitar-to-scales-chords", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "undefined", …}
1: {id: 8, name: "Advanced guitar skills with William Topa", slug: "advanced-guitar-skills-with-william-topa", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "Lorem ipsum dolor sit amet, consectetur adipiscing… laboris nisi ut aliquip ex ea commodo consequat.", …}
2: {id: 9, name: "Music production simplified", slug: "music-production-simplified", description: "We live in a unique and wonderful time where elect… going to give you a lifetime of awesome rockin’.", booking_details: "Lorem ipsum dolor sit amet, consectetur adipiscing… laboris nisi ut aliquip ex ea commodo consequat.", …}
length: 3
__proto__: Array(0)
tag: "Music"
updated_at: null
weight: null
This is part of a bigger object, the hierarchy looks like
[{ data, listings }, {data, listings}]
What I am wanting to do, is filter through the listings array and hide any listings that don't have a cost of "0.00"
Here is what i am trying,
<input type="checkbox" v-model="priceFilter" value="0.00" />
data() {
return {
this.priceFilter: []
}
},
computed: {
filteredTags() {
return this.tags.filter(tag => {
tag.listings.filter(listing => "0.00" === listing.cost);
//console.log(this.checkedPrice, listing.cost);
});
},
},
In the above I just trying to return the listings where the cost matches 0.00 with trigger it via the checkbox being checked but even that does not filter as I wish I still see all listings.
Anyone care to offer any advice?

With [...Array(this.props.heda[evKey][post])] you create an array which has as the first element the array this.props.heda[evKey][post]).
Maybe you wanted to say [...this.props.heda[evKey][post]] to create a clone of the array?

Because he is not able to find id in this.props.heda[evKey][post] object. So firstly you should console your this.props.heda[evKey][post] object after that I think you will get your actual problem.

Please try below snippet:
this.props.heda.map((evVal, evKey) => {
return evVal.map((postVal, postKey) => {
...
}
}
Now this.props.heda[evKey][postKey] will give you the expected object.

Bootstrap Table filter by string partial

I'm using the Bootstrap-table plugin (http://bootstraptable.wenzhixin.net.cn/documentation/) and I'm trying to filter by tags by utilizing the method filterby but can't figure out how to factor in multiple tags that has to come in as a string, separated by commas.
I created an example to illustrate what I'm attempting to achieve. For simplicity,
Here's the html:
<table id="table">
<thead>
<tr>
<th data-field="date">Date</th>
<th data-field="desc">Description</th>
<th data-field="tags">Tags</th>
</tr>
</thead>
</table>
<br>
<button id="filter-general">General</button>
<button id="filter-rotation">Rotation</button>
<button id="clear">clear</button>
Javascript:
var data = [{
"date": "2016-05-10",
"tags": "General, Research, Rotation",
"desc": "Nunc velit lectus, ornare vitae fringilla eget, vestibulum quis tortor."
},{
"date": "2016-04-22",
"tags": "General",
"desc": "Nunc velit lectus, ornare vitae fringilla eget, vestibulum quis tortor."
},{
"date": "2016-03-23",
"tags": "Research, Rotation",
"desc": "Nunc velit lectus, ornare vitae fringilla eget, vestibulum quis tortor."
},{
"date": "2015-11-01",
"tags": "Rotation",
"desc": "Nunc velit lectus, ornare vitae fringilla eget, vestibulum quis tortor."
},{
"date": "2016-08-15",
"tags": "General, Rotation",
"desc": "Nunc velit lectus, ornare vitae fringilla eget, vestibulum quis tortor."
}];
$(function() {
$table = $('#table');
$table.bootstrapTable({
data: data
});
$('#clear').click(function() {
$table.bootstrapTable('filterBy', {});
});
$('#filter-general').click(function() {
$table.bootstrapTable('filterBy', {
tags: "General"
});
});
$('#filter-rotation').click(function() {
$table.bootstrapTable('filterBy', {
tags: "Rotation"
});
});
});

Edit: Either by filterby method or from one of the filter extensions.

I think you are out of luck using the filterBy fuction. From the source code (https://github.com/wenzhixin/bootstrap-table/blob/develop/src/bootstrap-table.js):
var f = $.isEmptyObject(this.filterColumns) ? null : this.filterColumns;
// Check filter
this.data = f ? $.grep(this.options.data, function (item, i) {
for (var key in f) {
if ($.isArray(f[key]) && $.inArray(item[key], f[key]) === -1 ||
item[key] !== f[key]) {
return false;
}
}
return true;
}) : this.options.data;
where item[key] is your cell value and f[key] is your filter string. $.inArray is looking for the complete text of the cell in your filter strings.

i know, old session but just change check filter part to this:
for (var key in f) {
if (Array.isArray(f[key]) && !f[key].includes(item[key])) {
return false;
}
if(!Array.isArray(f[key]) ){
if(item[key].search(f[key])==-1){
return false
}
}
}

Let's say i'd like to re-invent CoffeeScript :) Or Python. Or Stylus, or YAML :)
I need some tool, which will turn my indentation-base syntax into abstract syntax tree. Google unfortunately knowns nothing about [indentation-based sytntax to AST]. Do you guys know any tool like this?
To be more specific, what I have
===source===
Lorem ipsum:
dolor sit amet:
consectetuer adipiscing elit
sed diam nonummy
nibh euismod tincidunt:
ut laoreet dolore
...and what I need:
===result===
[
{
directive: "Lorem ipsum",
content: [
{
directive: "dolor sit amet",
content: [
{directive: "consectetuer adipiscing elit", content: []}
]
},
{directive: "sed diam nonummy", content: []}
]
}, {
directive: "nibh euismod tincidunt",
content: [
{directive:"ut laoreet dolore", content: []}
]
}
]
It would be great, if you could recommend some tool like this. It would be awesome if this tool is written on python/javascript and display result as JSON.
It would be also cool if you can give a piece of advice about how to create this tool-of-a-dream by myself :)
Thanx!

It's simple enough to write this yourself using recursion. Here is one that creates a list -- I'll leave the dict version as an exercise for you.
import sys
import re
def DentArthurDent(fp, dents = 0, nextline = None):
'''Read from FP until EOF or an exdent
Return dict and next line'''
tree = []
while True:
line, nextline = nextline or fp.readline(), None
if not line:
return tree, ''
parts = re.match(r'(^ *)(.*)', line).group(1,2)
dent = len(parts[0])
if dent == dents:
tree.append(parts[1])
elif dent > dents:
child_tree, nextline = DentArthurDent(fp, dent, line)
tree.append(child_tree)
else:
return tree,line
import json
tree, _ = DentArthurDent(sys.stdin)
print json.dumps(tree, indent=4)
This input:
line 1
line 2
line 3
line 4
line 5
line 6
yields this output:
[
"line 1",
"line 2",
[
"line 3",
[
"line 4",
"line 5"
],
"line 6"
]
]
