如何搜索postgres的英文数字，但返回波斯语/阿拉伯语？

CREATE TEXT SEARCH CONFIGURATION persian_arabic_search (COPY = pg_catalog.simple);

CREATE FUNCTION english_to_persian_arabic(word text) RETURNS text AS $$
BEGIN
    -- 在这里编写将英文数字转换为波斯语/阿拉伯语的逻辑
    -- 例如，可以使用CASE语句进行转换
    RETURN CASE
        WHEN word = '1' THEN '۱'
        WHEN word = '2' THEN '۲'
        -- 其他数字的转换逻辑
        ELSE word
    END;
END;
$$ LANGUAGE plpgsql;

CREATE TEXT SEARCH DICTIONARY english_to_persian_arabic_dict (
    TEMPLATE = simple,
    DictFile = english_to_persian_arabic
);

ALTER TEXT SEARCH CONFIGURATION persian_arabic_search
    ALTER MAPPING FOR asciiword WITH english_to_persian_arabic_dict;

SELECT * FROM your_table
WHERE to_tsvector('persian_arabic_search', your_column) @@ to_tsquery('persian_arabic_search', '123');
