发现官方说明：Rime 全拼双拼混输

# 新建文件：double_pinyin_flypy.custom.yaml，将以下内容复制进即可。
patch:
# 在 engine/filters 插入长词优先的 Lua
engine/filters:
- lua_filter@corrector
- reverse_lookup_filter@radical_reverse_lookup
- lua_filter@search@radical_pinyin
- lua_filter@autocap_filter
- lua_filter@pin_cand_filter
- lua_filter@long_word_filter # 增加长词优先
- simplifier@emoji
- simplifier@traditionalize
- lua_filter@reduce_english_filter
- uniquifier
# 长词优先设置为提升 10 个词到第 1 个位置
long_word_filter:
count: 10
idx: 1
# 双拼不转换为全拼编码
translator/preedit_format: []
# xform 变形改为 derive 派生
