🚀 Getting Started

Add documents

package main

import (
    "fmt"
    "os"

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

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

    // Create an index if your index does not already exist
    _, err := client.Indexes().Create(meilisearch.CreateIndexRequest{
        UID: "books",
    })
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    documents := []map[string]interface{}{
        {"book_id": 123,  "title": "Pride and Prejudice"},
        {"book_id": 456,  "title": "Le Petit Prince"},
        {"book_id": 1,    "title": "Alice In Wonderland"},
        {"book_id": 1344, "title": "The Hobbit"},
        {"book_id": 4,    "title": "Harry Potter and the Half-Blood Prince"},
        {"book_id": 42,   "title": "The Hitchhiker's Guide to the Galaxy"},
    }

    updateRes, err := client.Documents("books").AddOrUpdate(documents) // => { "updateId": 0 }
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    fmt.Println(updateRes.UpdateID)
}

With the updateId, you can check the status (enqueued, processed or failed) of your documents addition using the update endpoint.

Basic Search

package main

import (
    "fmt"
    "os"

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

func main() {
    // MeiliSearch is typo-tolerant:
    searchRes, err := client.Search("books").Search(meilisearch.SearchRequest{
        Query: "harry pottre",
        Limit: 10,
    })
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    fmt.Println(searchRes.Hits)
}

JSON output:

{
  "hits": [{
    "book_id": 4,
    "title": "Harry Potter and the Half-Blood Prince"
  }],
  "offset": 0,
  "limit": 10,
  "processingTimeMs": 1,
  "query": "harry pottre"
}

Custom Search

All the supported options are described in the search parameters section of the documentation.

func main() {
    resp, err := client.Search(indexUID).Search(meilisearch.SearchRequest{
        Query: "prince",
        AttributesToHighlight: []string{"*"},
        Filters: "book_id > 10"
    })
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    fmt.Println(searchRes.Hits)
}

JSON output:

{
    "hits": [
        {
            "book_id": 456,
            "title": "Le Petit Prince",
            "_formatted": {
                "book_id": 456,
                "title": "Le Petit <em>Prince</em>"
            }
        }
    ],
    "offset": 0,
    "limit": 1,
    "processingTimeMs": 0,
    "query": "prince"
}
