Multiple entry conditions can be combined together.
collection.find(doc! {"Age": {"$gt": 10}, "Height": {"$not": {"$eq": 190}}}).unwrap();
The example above finds the documents with Age
being more than 10
as well as Height
being not equal to 190
.
The complete code is presented below:
use polodb_core::{bson::doc, Database};
fn main() {
let db = Database::open_memory().unwrap();
let collection = db.collection("name_of_the_collection");
let docs = [
doc! {
"Name": "Alice",
"Age": 21,
"Height": 190,
},
doc! {
"Name": "Bob",
"Age": 20,
"Height": 180,
},
doc! {
"Name": "Cat",
"Age": 3,
},
];
collection.insert_many(docs).unwrap();
let docs_found = collection
.find(doc! {"Age": {"$gt": 10}, "Height": {"$not": {"$eq": 190}}})
.unwrap();
for doc in docs_found {
println!("{:#?}", doc.unwrap());
}
}
Output:
Document({
"Name": String(
"Bob",
),
"Age": Int32(
20,
),
"Height": Int32(
180,
),
"_id": ObjectId(
"66d7152ac2b07e12a63d66ca",
),
})
