MYSQL搜索正确的单词|修正拼写错误

问题描述

我有一个表dictionary，其中包含类似单词的列表:

I have a table dictionary which contains a list of words Like:

   ID|word
   ---------
    1|hello
    2|google
    3|similar
    ...

所以我想如果有人写这样的文本

so i want if somebody writes a text like

"hela iam正在为gogle寻找类似引擎".

"helo iam looking for simlar engines for gogle".

现在我要检查数据库中是否存在每个单词，如果不存在，应该给我一个类似的词.例如:helo = hello, simlar = similar, gogle = google.好吧，我想修复拼写错误.在我的数据库中，我有所有英语单词的完整词典.我找不到任何对我有帮助的mysql函数. LIKE对我的情况没有帮助.

Now I want to check every word if it exists in the database, if not it shouldget me the similar word for the word. For example: helo = hello, simlar = similar, gogle = google.Well, i want to fix the spelling errors. In my database i have a full dictionary of all english words. I coudn't find any mysql function which helps me. LIKE isn't helpfull in my situation.
