在Java中實現分詞搜索查詢功能通常可以使用開源的分詞工具，比如使用Lucene或者Elasticsearch。

1. 使用Lucene實現分詞搜索查詢功能： Lucene是一個開源的全文檢索引擎庫，提供了豐富的API用于分詞、索引和搜索文本數據。以下是一個簡單的示例代碼，演示如何使用Lucene實現分詞搜索查詢功能：

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.queryparser.classic.QueryParser;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.ScoreDoc;
import org.apache.lucene.search.TopDocs;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.RAMDirectory;

public class LuceneExample {

    public static void main(String[] args) {
        try {
            // 創建索引
            Directory directory = new RAMDirectory();
            Analyzer analyzer = new StandardAnalyzer();
            IndexWriter indexWriter = new IndexWriter(directory, analyzer, IndexWriter.MaxFieldLength.UNLIMITED);
            
            Document doc = new Document();
            doc.add(new Field("content", "Hello World", Field.Store.YES, Field.Index.ANALYZED));
            indexWriter.addDocument(doc);
            indexWriter.commit();
            indexWriter.close();
            
            // 搜索
            IndexSearcher indexSearcher = new IndexSearcher(directory);
            QueryParser parser = new QueryParser("content", analyzer);
            Query query = parser.parse("Hello");
            
            TopDocs topDocs = indexSearcher.search(query, 10);
            ScoreDoc[] scoreDocs = topDocs.scoreDocs;

            for (ScoreDoc scoreDoc : scoreDocs) {
                Document document = indexSearcher.doc(scoreDoc.doc);
                System.out.println(document.get("content"));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

2. 使用Elasticsearch實現分詞搜索查詢功能： Elasticsearch是一個基于Lucene的開源搜索引擎，提供了RESTful API用于索引和搜索文檔。以下是一個簡單的示例代碼，演示如何使用Elasticsearch實現分詞搜索查詢功能：

import org.elasticsearch.action.search.SearchRequest;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.builder.SearchSourceBuilder;

public class ElasticsearchExample {

    public static void main(String[] args) {
        try {
            RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", 9200, "http")));
            
            SearchRequest searchRequest = new SearchRequest("index_name");
            SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
            searchSourceBuilder.query(QueryBuilders.matchQuery("content", "Hello"));
            searchRequest.source(searchSourceBuilder);
            
            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
            
            for (SearchHit hit : searchResponse.getHits().getHits()) {
                Map<String, Object> sourceAsMap = hit.getSourceAsMap();
                System.out.println(sourceAsMap.get("content"));
            }
            
            client.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

以上代碼示例演示了如何使用Lucene和Elasticsearch實現分詞搜索查詢功能。通過使用這些開源工具，可以方便地實現復雜的文本搜索功能。
