🚀 Getting Started

Add documents

package main

import (
	"fmt"
	"os"

	"github.com/meilisearch/meilisearch-go"
)

func main() {
	client := meilisearch.NewClient(meilisearch.ClientConfig{
                Host: "http://127.0.0.1:7700",
                APIKey: "masterKey",
        })
	// 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.taskID)
}

With the taskID, you can check the status (enqueued, processing, succeeded or failed) of your documents addition using the task endpoint.

Basic Search

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:

{
  "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 section of the documentation.

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:

{
    "hits": [
        {
            "id": 2,
            "title": "Wonder Woman",
            "genres": ["Action", "Adventure"],
            "_formatted": {
                "id": 2,
                "title": "<em>Wonder</em> 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.

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.

Then, you can perform the search:

searchRes, err := index.Search("wonder",
    &meilisearch.SearchRequest{
        Filter: "id > 1 AND genres = Action",
    })

{
  "hits": [
    {
      "id": 2,
      "title": "Wonder Woman",
      "genres": ["Action","Adventure"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 1,
  "processingTimeMs": 0,
  "query": "wonder"
}
