Lucene的基本用法

创建lucene索引

 1 //1. path
 2 string indexPath=@"/ui/index/";
 3 
 4 //2. StandarAnalyzer
 5 Lucene.Net.Analysis.Standard.StandarAnalyzer sa=new StandarAnalyzer();
 6 
 7 //3. IndexWriter
 8 IndexWriter iw=new IndexWriter(mapPath(indexPath),sa,true);
 9 
10 //4. Document
11 Document doc=new Document();
12 
13 //5. Field 
14 Field f=newFiled("id",val,Field.Store.Yes,field.index.UN_TOKENIZED);
15 
16 doc.Add(f);
17 iw.addDocument(doc);

读取lucene索引数据

1. //Path,IndexReader,field_key
IndexReader reader=IndexReader.Open(MapPath(indexPath);
string field="id";
// Searcher
2.Search se=new IndexSearcher(reader);

//Analyzer 
3.Analyzer an=new StandarAnalyzer();

//QueryParser
4.QueryParser  p=new QueryParser(field,an);
                         p2=new QueryParser(field2,an);

//BooleanQuery
5.BooleanQuery b=new BooleanQuery();
//Query Term
    //Term t=new Term("id",filed);
      q=new WildcardQuery(t);
     Query q=p.parse(filed);
            q2=p2.parse(filed2);
b.add(q,booleanClause.Occur.Must/Should);


//Hit
6. Hits myhit=se.search(b);
for循环{
Docment doc=myHit.Doc(i);
doc.Get("id").tostring();
}
