我在 lucene 提升方面遇到问题,我正在尝试提升与指定的(名字)字段匹配的特定文档我已经发布了部分代码
private static Document createDoc(String lucDescription,String primaryk,String specialString){
Document doc = new Document();
doc.add(new Field("lucDescription",lucDescription, Field.Store.NO, Field.Index.TOKENIZED));
doc.add(new Field("primarykey",primaryk,Field.Store.YES,Field.Index.NO));
doc.add(new Field("specialDescription",specialString, Field.Store.NO, Field.Index.UN_TOKENIZED));
doc.setBoost ((float)(0.00001));
if (specialString.equals("chris"))
doc.setBoost ((float)(100000.1));
return doc;
}
为什么这不起作用?
public static String dbSearch(String searchString){
List<String> pkList = new ArrayList<String>();
String conCat="(";
try{
String querystr = searchString;
Query query = new QueryParser("lucDescription", new StandardAnalyzer()).parse(querystr);
IndexSearcher searchIndex = new IndexSearcher("/home/athreya/docsIndexFile");
// Index of the User table--> /home/araghu/aditya/indexFile.
Hits hits = searchIndex.search(query);
System.out.println("Found " + hits.length() + " hits.");
for(int iterator=0;iterator<hits.length();iterator++) {
String primKey=hits.doc(iterator).get("primarykey");
System.out.println(primKey);
pkList.add(primKey);
}
searchIndex.close();
提前谢谢你
