 This project is intended to be a modern, from-the-ground-up, maintainable alternative to [GoldenDict](https://github.com/goldendict/goldendict)(-[ng](https://github.com/xiaoyifang/goldendict-ng)), developed with Flask and React.

 - The wildcard characters are `^` and `+` (instead of `%` and `_` of SQL or the more traditional `*` and `?`) for technical reasons. Hint: imagine `%` and `_` are shifted one key to the right on an American keyboard.
 - This project creates a back-up of DSL dictionaries, overhauls[^3] them and _silently overwrites_ the original files. So after adding a DSL dictionary to SilverDict, it may no longer work with GoldenDict.
 - During the indexing process of DSL dictionaries, the memory usage could reach as high as 1.5 GiB (tested with the largest DSL ever seen, the _Encyclopædia Britannica_), and even after that the memory used remains at around 500 MiB. Restart the server process and the memory usage will drop to a few MiB. (The base server with no dictionaries loaded uses around 50 MiB of memory.)
-- Both-sides suggestion matching is implemented with an $n$-gram based method, where $n = 4$, meaning that it will only begin working when the query is equal to or longer than 4 characters. This feature is disabled by default, and can be enabled by editing `~/.silverdict/preferences.yaml` and create the ngram table in the settings menu. This process could be slow. You have to do this manually each time you add a new dictionary.

 - Morphology analysis (word stemming & spelling suggestions) is disabled unless you have installed the Python package `hunspell`, which could be non-trivial on some platforms. On Termux you can try out the script `termux_setup.sh` (Please ensure you have run `termux-setup-storage` before running the script).
-- To ensure cross-platform compatibility, the morphology dictionaries (Hunspell dictionaries with .aff and .dic files) should be placed into `~/.silverdict/hunspell`. Each dictionary's name must be `[language code].aff/dic`, e.g. `en.aff` & `en.dic`; `en_GB.aff` will be ignored. These dictionaries are usually distributed as myspell/hunspell data packages on Linux and can be found in `/usr/share/hunspell` or `/usr/share/myspell`. Please read [this](https://github.com/hunspell/hunspell#dictionaries) to see where to get Hunspell dictionaries if you are on other platforms. Warning: these dictionaries use a huge amount of memory despite their small size, so please add them only when you really need them.
