## 📖 Documentation
This readme contains all the documentation you need to start using this Meilisearch SDK.
For general information on how to use Meilisearch—such as our API reference, tutorials, guides, and in-depth articles—refer to our [main documentation website](https://www.meilisearch.com/docs/).
## ⚡ Supercharge your Meilisearch experience
Say goodbye to server deployment and manual updates with [Meilisearch Cloud](https://www.meilisearch.com/cloud?utm_campaign=oss&utm_source=github&utm_medium=meilisearch-go). Get started with a 14-day free trial! No credit card required.
## 🔧 Installation
With `go get` in command line:
```bash
go get github.com/meilisearch/meilisearch-go
```
### Run Meilisearch
There are many easy ways to [download and run a Meilisearch instance](https://www.meilisearch.com/docs/learn/getting_started/installation).
For example, using the `curl` command in [your Terminal](https://itconnect.uw.edu/learn/workshops/online-tutorials/web-publishing/what-is-a-terminal/):
```bash
# Install Meilisearch
curl -L https://install.meilisearch.com | sh
# Launch Meilisearch
./meilisearch --master-key=masterKey
```
NB: you can also download Meilisearch from **Homebrew** or **APT** or even run it using **Docker**.
## 🚀 Getting started
#### Add documents
```go
package main
import (
"fmt"
"os"
"github.com/meilisearch/meilisearch-go"
)
func main() {
client := meilisearch.New("http://localhost:7700", meilisearch.WithAPIKey("foobar"))
// An index is where the documents are stored.
index := client.Index("movies")
// If the index 'movies' does not exist, Meilisearch creates it when you first add the documents.
documents := []map[string]interface{}{
{ "id": 1, "title": "Carol", "genres": []string{"Romance", "Drama"} },
{ "id": 2, "title": "Wonder Woman", "genres": []string{"Action", "Adventure"} },
{ "id": 3, "title": "Life of Pi", "genres": []string{"Adventure", "Drama"} },
{ "id": 4, "title": "Mad Max: Fury Road", "genres": []string{"Adventure", "Science Fiction"} },
{ "id": 5, "title": "Moana", "genres": []string{"Fantasy", "Action"} },
{ "id": 6, "title": "Philadelphia", "genres": []string{"Drama"} },
}
task, err := index.AddDocuments(documents)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
fmt.Println(task.TaskUID)
}
```
With the `taskUID`, you can check the status (`enqueued`, `canceled`, `processing`, `succeeded` or `failed`) of your documents addition using the [task endpoint](https://www.meilisearch.com/docs/reference/api/tasks).
#### Basic Search
```go
package main
import (
"fmt"
"os"
"github.com/meilisearch/meilisearch-go"
)
func main() {
// Meilisearch is typo-tolerant:
searchRes, err := client.Index("movies").Search("philoudelphia",
&meilisearch.SearchRequest{
Limit: 10,
})
if err != nil {
fmt.Println(err)
os.Exit(1)
}
fmt.Println(searchRes.Hits)
}
```
JSON output:
```json
{
"hits": [{
"id": 6,
"title": "Philadelphia",
"genres": ["Drama"]
}],
"offset": 0,
"limit": 10,
"processingTimeMs": 1,
"query": "philoudelphia"
}
```
#### Custom Search
All the supported options are described in the [search parameters](https://www.meilisearch.com/docs/reference/api/search#search-parameters) section of the documentation.
```go
func main() {
searchRes, err := client.Index("movies").Search("wonder",
&meilisearch.SearchRequest{
AttributesToHighlight: []string{"*"},
})
if err != nil {
fmt.Println(err)
os.Exit(1)
}
fmt.Println(searchRes.Hits)
}
```
JSON output:
```json
{
"hits": [
{
"id": 2,
"title": "Wonder Woman",
"genres": ["Action", "Adventure"],
"_formatted": {
"id": 2,
"title": "Wonder Woman"
}
}
],
"offset": 0,
"limit": 20,
"processingTimeMs": 0,
"query": "wonder"
}
```
#### Custom Search With Filters
If you want to enable filtering, you must add your attributes to the `filterableAttributes` index setting.
```go
task, err := index.UpdateFilterableAttributes(&[]string{"id", "genres"})
```
You only need to perform this operation once.
Note that Meilisearch will rebuild your index whenever you update `filterableAttributes`. Depending on the size of your dataset, this might take time. You can track the process using the [task status](https://www.meilisearch.com/docs/learn/advanced/asynchronous_operations).
Then, you can perform the search:
```go
searchRes, err := index.Search("wonder",
&meilisearch.SearchRequest{
Filter: "id > 1 AND genres = Action",
})
```
```json
{
"hits": [
{
"id": 2,
"title": "Wonder Woman",
"genres": ["Action","Adventure"]
}
],
"offset": 0,
"limit": 20,
"estimatedTotalHits": 1,
"processingTimeMs": 0,
"query": "wonder"
}
```
#### Customize Client
The client supports many customization options:
- `WithCustomClient` sets a custom `http.Client`.
- `WithCustomClientWithTLS` enables TLS for the HTTP client.
- `WithAPIKey` sets the API key or master [key](https://www.meilisearch.com/docs/reference/api/keys).
- `WithContentEncoding` configures [content encoding](https://www.meilisearch.com/docs/reference/api/overview#content-encoding) for requests and responses. Currently, gzip, deflate, and brotli are supported.
- `WithCustomRetries` customizes retry behavior based on specific HTTP status codes (`retryOnStatus`, defaults to 502, 503, and 504) and allows setting the maximum number of retries.
- `DisableRetries` disables the retry logic. By default, retries are enabled.
```go
package main
import (
"net/http"
"github.com/meilisearch/meilisearch-go"
)
func main() {
client := meilisearch.New("http://localhost:7700",
meilisearch.WithAPIKey("foobar"),
meilisearch.WithCustomClient(http.DefaultClient),
meilisearch.WithContentEncoding(meilisearch.GzipEncoding, meilisearch.BestCompression),
meilisearch.WithCustomRetries([]int{502}, 20),
)
}
```
