Usage Example
package main
import (

"log"
"time"
"github.com/RediSearch/redisearch-go/redisearch"
)
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>
