本文介绍如何通过修改配置文件来优化CJK字符的索引功能，包括调整n-gram长度、设置n-gram字符范围及短语边界等参数。

修改默认配置，搜索CJK，找到如下去掉注释，改成如下：

        # n-gram length to index, for CJK indexing
        # only supports 0 and 1 for now, other lengths to be implemented
        # optional, default is 0 (disable n-grams)
        #
        ngram_len               = 1


        # n-gram characters list, for CJK indexing
        # optional, default is empty
        #
        ngram_chars             = U+3000..U+2FA1F

        # phrase boundary characters list
        # optional, default is empty
        #
        phrase_boundary         = ., ?, !, U+2026 # horizontal ellipsis


        # phrase boundary word position increment
        # optional, default is 0
        #
        # phrase_boundary_step  = 100
