I am using mongodb’s sample movie database (https://docs.atlas.mongodb.com/sample-data/sample-mflix#std-label-sample-mflix) to experiment with mongodb’s autocomplete functionality. The search always returns an empty array. I am using Atlas on the free tier.
I have set up a Search Index as follows:
{
"mappings": {
"dynamic": false,
"fields": {
"title": [
{
"minGrams": 3,
"tokenization": "edgeGram",
"type": "autocomplete"
}
]
}
}
}
The model and the search query are setup as follows:
// Creating the Movies model
const Movies = mongoose.model("Movies", new mongoose.Schema({}), "movies");
// Impplementing autocomplete search
app.get("/search", async (req, res) => {
try {
let result = await Movies.aggregate([
{
$search: {
autocomplete: {
path: "title",
query: req.query.title,
fuzzy: {
maxEdits: 2,
prefixLength: 3,
},
},
},
},
]);
res.status(200).json({
status: "success",
results: result.length,
data: { result },
});
} catch (error) {
console.log(error);
}
});
I am using postman to run test queries and a sample query is: 127.0.0.1:3030/search?title=black
The model can be queried using .find(), for example, and returns the full collection of documents.
Any and all help is greatly appreciated.
