如何在JAVA中搜索阿拉伯语文本？

Question

我在带有变音符号的数据库中有阿拉伯语文本.当我输入阿拉伯语搜索某些字符串时,它没有变音符号,它肯定与数据库字符串不匹配.它在没有变音符号的情况下正常工作.有没有办法在文本上运行它与变音符号???

Answer 1

有没有办法在文本上运行它与变音符号???

很不幸的是,不行.像MIE说:

阿拉伯语变音符号是字符

所以据我所知,这是不可能的.

MIE的答案很难实现,如果您更改数据库中的任何内容,将无法获得更新.

您可以查看Apache Lucene搜索软件库.我不确定,但看起来它可以解决你的问题.

或者你需要从你的数据库中删除所有的变音符号,然后只需使用像这样的小型阿拉伯语规范化器,你就可以使用或不使用变音符号来查询它:

我发现这样做更好。为此而获得的所有奖励：

public class ArabicDiacritics {

    private String input;
    private final String output;

    /**

     */
    public ArabicDiacritics(String input){
        this.input=input;
        this.output=normalize();
    }

    /**
     * normalize Method
     * @return String
     */
    private String normalize(){

        input = Normalizer.normalize(input, Form.NFKD)
                .replaceAll("\\p{M}", "");

        return input;
    }

    /**

    public String getOutput() {
        return output;
