要解决Amazon CloudSearch中的重音词问题，可以使用字符过滤器和自定义分析器来实现。下面是一个示例代码，演示了如何在Amazon CloudSearch中处理重音词。

1. 首先，创建一个字符过滤器，用于将重音字符转换为非重音字符。可以使用Java的Normalizer类来实现这一点。

import java.text.Normalizer;

public class AccentRemovalCharFilter implements CharFilter {
    private CharStream input;

    public AccentRemovalCharFilter(CharStream input) {
        this.input = input;
    }

    public int read(char[] cbuf, int off, int len) throws IOException {
        int bytesRead = input.read(cbuf, off, len);
        for (int i = off; i < off + bytesRead; i++) {
            cbuf[i] = removeAccent(cbuf[i]);
        }
        return bytesRead;
    }

    private char removeAccent(char c) {
        String s = String.valueOf(c);
        String normalized = Normalizer.normalize(s, Normalizer.Form.NFD);
        String removed = normalized.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
        return removed.charAt(0);
    }
}

2. 然后，创建一个自定义分析器，使用上面定义的字符过滤器来处理重音词。可以使用Java的Analyzer类来实现这一点。

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.core.LowerCaseFilter;
import org.apache.lucene.analysis.standard.StandardTokenizer;

public class AccentRemovalAnalyzer extends Analyzer {
    @Override
    protected TokenStreamComponents createComponents(String fieldName) {
        StandardTokenizer tokenizer = new StandardTokenizer();
        TokenStream tokenStream = new AccentRemovalCharFilter(tokenizer);
        tokenStream = new LowerCaseFilter(tokenStream);

        return new TokenStreamComponents(tokenizer, tokenStream);
    }
}

3. 最后，将自定义分析器应用于Amazon CloudSearch的搜索域。

import com.amazonaws.services.cloudsearchv2.AmazonCloudSearchClient;
import com.amazonaws.services.cloudsearchv2.model.DefineIndexFieldRequest;
import com.amazonaws.services.cloudsearchv2.model.IndexFieldType;
import com.amazonaws.services.cloudsearchv2.model.IndexField;

public class CloudSearchAccentRemoval {
    public static void main(String[] args) {
        // 创建Amazon CloudSearch客户端
        AmazonCloudSearchClient client = new AmazonCloudSearchClient();

        // 定义一个新的搜索域
        IndexField indexField = new IndexField()
                .withIndexFieldName("text")
                .withIndexFieldType(IndexFieldType.Text)
                .withAnalyzer(new AccentRemovalAnalyzer());

        // 创建一个DefineIndexFieldRequest对象，并设置搜索域
        DefineIndexFieldRequest request = new DefineIndexFieldRequest()
                .withDomainName("your-cloudsearch-domain")
                .withIndexField(indexField);

        // 发送DefineIndexField请求
        client.defineIndexField(request);
    }
}

上述示例代码演示了如何使用字符过滤器和自定义分析器来处理Amazon CloudSearch中的重音词问题。将上面的代码片段替换为真实的Amazon CloudSearch客户端代码，并将其与您的CloudSearch域一起使用，以处理重音词。
