java - 如何在 JAVA 中对阿拉伯文本进行搜索？

Question

我在数据库中有带有变音符号的阿拉伯文本。当我输入阿拉伯语搜索一些字符串时，它没有变音符号，这肯定与数据库字符串不匹配。它在没有变音符号的文本上运行良好。有没有办法在带有变音符号的文本上运行它？？？

Answer 1

is there any way to run it on text with diacritics ???

不幸的是没有。就像 MIE 说的:

Arabic diacritics are characters

所以据我所知这是不可能的。

MIE 的答案将难以实现，并且如果您更改数据库中的任何内容，将根本不可能获得更新。

你也许可以看看 Apache Lucene search software Library .我不确定，但看起来它可以解决您的问题。

或者您需要从数据库中删除所有变音符号，然后您就可以通过使用像 this one 这样的小型阿拉伯语规范器来查询带有或不带有变音符号的数据库。 :

        this.input=input;
        this.output=normalize();
    }
