# Vectoria
Vectoria is an embedded vector database for simple use cases. It implements LSH (Locality-Sensitive Hashing).
Here’s a complete example:
```go
package main
import (
"log"
"github.com/caiodallaqua/vectoria"
)
func main() {
var (
indexName = "hello-world"
// Vector to be stored.
vec = []float64{1.1, 0.2}
// Key to be retrieved.
key = "my-key"
// Let's add a small deviation to vec,
// so we can see a match.
queryVec = []float64{vec[0] + 0.1, vec[1] + 0.1}
// Only similarities >= thresold.
threshold = 0.9
// Upper limit on how many items to retrieve.
k uint32 = 1
)
dbConfig := vectoria.DBConfig{
Path: "", // In-memory storage.
LSH: []vectoria.LSHConfig{{
IndexName: indexName,
NumRounds: 5,
NumHyperPlanes: 2,
SpaceDim: 2, // Length of your vectors.
}},
}
db, err := vectoria.New(dbConfig)
if err != nil {
log.Fatalf("unable to create database: %s", err)
return
}
if err = db.Add(key, vec, indexName); err != nil {
log.Fatalf("unable to add key: %s", err)
return
}
res, err := db.Get(queryVec, threshold, k, indexName)
if err != nil {
log.Fatalf("unable to get key: %s", err)
return
}
log.Println("retrieval results:")
for index, key := range res {
log.Printf("\tindex: %v", index)
log.Printf("\tkeys: %v", key)
}
}
```
