Indexing

	message := struct{
		From: "[email protected]",
		Body: "bleve indexing is easy",
	}

	mapping := bleve.NewIndexMapping()
	index, _ := bleve.New("example.bleve", mapping)
	index.Index(message)

Querying

	index, _ := bleve.Open("example.bleve")
	query := bleve.NewSyntaxQuery("bleve")
	searchRequest := bleve.NewSearchRequest(query)
	searchResult, _ := index.Search(searchRequest)
