Lucence问题，急求

Question

import java.io.*;
import org.apache.lucene.search.*;
import org.apache.lucene.index.Term;
import org.apache.lucene.document.*;public class Query { private String INDEX_STORE_PATH = "D:/JEEworkspace/Preprocess/indexes";

private IndexSearcher searcher;

private BooleanQuery query; public String[] getQueryResult(String[] keys) throws IOException{

searcher = new IndexSearcher(INDEX_STORE_PATH);
query = new BooleanQuery();
if(keys == null){
return null;
}
int length = keys.length;
TermQuery[] term = new TermQuery[length]; for(int i = 0; i < length; i++){
term[i] = new TermQuery(new Term("context", keys[i]));
        query.add(term[i], BooleanClause.Occur.MUST);
}
// Sort sort = new Sort(new SortField("score"));
Hits hits = searcher.search(query);

length = hits.length();
String[] result = new String[length];
        for(int i = 0; i < length; i++){
         Document doc = hits.doc(i);
         String tmp = doc.getField("title").stringValue();
         tmp = tmp + "|" + doc.getField("url").stringValue();
         tmp = tmp + "|" + doc.getField("context").stringValue();
         result[i] = tmp;
        }
        
        return result;
        
}
}
然后在页面调用会报如下错误
严重: Servlet.service() for servlet jsp threw exception

Answer 1

经查证是
searcher = new IndexSearcher(INDEX_STORE_PATH);
 这一句报的错误
java.io.FileNotFoundException: no segments* file found: files:

高手指点下·

看上面的错误是lucene版本不兼容造成的，你查一下你的索引文件和你的程序是不是一个版本的jar
