How to match the two strings with and without including spaces
You can compare so:
let val1 = 'cell phones';
let val2 = 'cellphones';
console.log(val1.replace(/\s/g, '') === val2.replace(/\s/g, '')) // true
//OR
console.log(val1.split(' ').join('') === val2.split(' ').join('')) // true
If you need some aggregation trick then you can try this
db.collection.aggregate([
{ "$project": {
"name": {
"$reduce": {
"input": { "$split": ["$name", " "] },
"initialValue": "",
"in": { "$concat": ["$$value", "$$this"] }
}
}
}},
{ "$match": { "name": "cellphones" }}
])
You can test it Here
You can first start by stripping out the spaces on both the strings before comparing them, for example:
let a = "cell phone";
let b = "cellphone";
let c = "cell phones"
const stripSpaces = s => s.replace(/\s/g, '');
// compare
console.log(stripSpaces(a) == stripSpaces(b)); // true
console.log(stripSpaces(a) == stripSpaces(c)); // false
