)

func ExampleClient() {

    // Create a client. By default a client is schemaless
    // unless a schema is provided when creating the index
    c := redisearch.NewClient("localhost:6379", "myIndex")

    // Create a schema
    sc := redisearch.NewSchema(redisearch.DefaultOptions).
        AddField(redisearch.NewTextField("body")).
        AddField(redisearch.NewTextFieldOptions("title", redisearch.TextFieldOptions{Weight: 5.0, Sortable: true})).
        AddField(redisearch.NewNumericField("date"))

    // Drop an existing index. If the index does not exist an error is returned
    c.Drop()

    // Create the index with the given schema
    if err := c.CreateIndex(sc); err != nil {
        log.Fatal(err)
    }

    // Create a document with an id and given score
    doc := redisearch.NewDocument("doc1", 1.0)
    doc.Set("title", "Hello world").
        Set("body", "foo bar").
        Set("date", time.Now().Unix())

    // Index the document. The API accepts multiple documents at a time
    if err := c.Index([]redisearch.Document{doc}...); err != nil {
        log.Fatal(err)
    }

    // Searching with limit and sorting
    docs, total, err := c.Search(redisearch.NewQuery("hello world").
        Limit(0, 2).
        SetReturnFields("title"))

    fmt.Println(docs[0].Id, docs[0].Properties["title"], total, err)
    // Output: doc1 Hello world 1 <nil>
