整合到bleve，发现没起作用

[senlinmuvs]

按照demo像下面这样不行，分词效果还是bleve默认的：

func (h *CreateIndexHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
	// find the name of the index to create
	var indexName string
	if h.IndexNameLookup != nil {
		indexName = h.IndexNameLookup(req)
	}
	if indexName == "" {
		showError(w, req, "index name is required", 400)
		return
	}

	indexMapping := bleve.NewIndexMapping()

	//
	err := indexMapping.AddCustomTokenizer("gojieba",
		map[string]interface{}{
			"dictpath":     gojieba.DICT_PATH,
			"hmmpath":      gojieba.HMM_PATH,
			"userdictpath": gojieba.USER_DICT_PATH,
			"type":         "gojieba",
			"idf":          gojieba.IDF_PATH,
			"stop_words":   gojieba.STOP_WORDS_PATH,
		},
	)
	if err != nil {
		panic(err)
	}
	err = indexMapping.AddCustomAnalyzer("gojieba",
		map[string]interface{}{
			"type":      "gojieba",
			"tokenizer": "gojieba",
		},
	)
	if err != nil {
		panic(err)
	}
	indexMapping.DefaultAnalyzer = "gojieba"

	// read the request body
	requestBody, err := ioutil.ReadAll(req.Body)
	if err != nil {
		showError(w, req, fmt.Sprintf("error reading request body: %v", err), 400)
		return
	}

	// interpret request body as index mapping
	if len(requestBody) > 0 {
		err := json.Unmarshal(requestBody, &indexMapping)
		if err != nil {
			showError(w, req, fmt.Sprintf("error parsing index mapping: %v", err), 400)
			return
		}
	}

	newIndex, err := bleve.New(h.indexPath(indexName), indexMapping)
	if err != nil {
		showError(w, req, fmt.Sprintf("error creating index: %v", err), 500)
		return
	}
	newIndex.SetName(indexName)
	bhttp.RegisterIndexName(indexName, newIndex)
	rv := struct {
		Status string `json:"status"`
	}{
		Status: "ok",
	}
	mustEncode(w, rv)
}
