I am managing a simple collection with fields for name, last name, category, age, and city. I am looking for an efficient way to perform multiple search and filter operations on these elements within a table. For example, filtering by name and age, age and city, or all of the above combined. Here is an example of my table: my table
What is the most optimal way to implement multiple filters in MongoDB and Meteor without using a search engine package in my case?
This is my preferred method for conducting searches, as it helps me find similar results as well. For example, if my result contains the letter "A," searching for "A" will display everything with that letter until I narrow it down further.
It's important to note that you may want to convert the search value and search keys to lowercase, as "A" is not equal to "a" and won't return any results.
I also included an integer value just in case that question arises.
let collection = yourCollection.find({
"nom": {
$regex: ".*CONDITION_VALUE.*"
},
"prenom": {
$regex: ".*CONDITION_VALUE.*"
},
"categorie": {
$regex: ".*CONDITION_VALUE.*"
},
"age": {
$gt: minAge,
$lt: maxAge
},
"ville": {
$regex: ".*CONDITION_VALUE.*"
}
});
When utilizing direct queries in MongoDB, you have access to a variety of examples:
To check for the existence of a field, you can use the $exist operator:
db.collectionName.find({fieldName: {$exists: true}})
If you are searching for a specific field value:
db.collectionName.find({'fieldName': 'value'})
A combination of $or and $exist can be implemented like this:
db.collectionName.find({ $or: [ {name: {$exists: true}}, {age: {$exists: true}} ] })
For multiple $or conditions, you can execute the following query:
db.collectionName.find({ $or: [ {name: {$exists: true}}, {age: {$exists: true}} ] },
{ $or: [ {age: {$exists: true}}, {city: {$exists: true}} ] })
