message UserHistory

optional string key = 1
optional string value = 2
optional string description = 6
optional uint32 suggestion_freq = 3
how many times the candidate is selected.
optional uint32 conversion_freq_deprecated = 5
This field is kept for backward compatibility. We do not distinguish suggestion and conversion mode. When loading old proto, max(conversion_freq_deprecated, suggestion_freq) is set to suggestion_freq.
optional uint32 shown_freq = 22
how many times the candidate is shown on commit event
optional uint64 last_access_time = 4
repeated NextEntry next_entries_deprecated = 7
list entries which were input just after this entry. This field is no longer used. uses `next_entry_fps`.
repeated fixed64 next_entry_fps = 23
list of entry-fps that were input just after this entry. uses fixed64 and packed as Fp cannot be compressed. It won't result in an error, but duplicates aren't allowed. The fps are stored to operate as an LRU (Least Recently Used) cache. The front element is the oldest, and the back element is the newest.
optional bool removed = 8
This entry is removed.
repeated fixed32 inner_segment_boundary = 24
Inner segment boundary. See converter/inner_segment.h
optional bool allow_partial_match = 25
Allow the entry to be a content key/value of other segment.
optional uint32 attributes = 26
This field is used to hold various information for ranking and filtering. It is intended for internal use only and should be cleared during serialization.

Used in: Entry

optional uint32 entry_fp = 1
Just store the Fingerprint32(key + "\t" + value) |entry| is used as the key of LRU cache
