Indexing

    config := bluge.DefaultConfig(path)
    writer, err := bluge.OpenWriter(config)
    if err != nil {
        log.Fatalf("error opening writer: %v", err)
    }
    defer writer.Close()

    doc := bluge.NewDocument("example").
        AddField(bluge.NewTextField("name", "bluge"))

    err = writer.Update(doc.ID(), doc)
    if err != nil {
        log.Fatalf("error updating document: %v", err)
    }

Querying

    reader, err := writer.Reader()
    if err != nil {
        log.Fatalf("error getting index reader: %v", err)
    }
    defer reader.Close()

    query := bluge.NewMatchQuery("bluge").SetField("name")
    request := bluge.NewTopNSearch(10, query).
        WithStandardAggregations()
    documentMatchIterator, err := reader.Search(context.Background(), request)
    if err != nil {
        log.Fatalf("error executing search: %v", err)
    }
    match, err := documentMatchIterator.Next()
    for err == nil && match != nil {
        err = match.VisitStoredFields(func(field string, value []byte) bool {
            if field == "_id" {
                fmt.Printf("match: %s\n", string(value))
            }
            return true
        })
        if err != nil {
            log.Fatalf("error loading stored fields: %v", err)
        }
        match, err = documentMatchIterator.Next()
    }
    if err != nil {
        log.Fatalf("error iterator document matches: %v", err)
