Hi~. I hava a question about lucene incremental indexing. I want to do incremental indexing my goods data. For example, I have 4 products datas with "GOOD_ID","NAME","PRICE","CREATEDATE","UPDATEDATE" colunms.
1, ipod, 30000, 2008-11-10:11:00, 2008-11-10:11:00 2, java book, 20000, 2008-11-10:11:00, 2008-11-10:11:00 3, calendar, 10000, 2008-11-10:11:00, 2008-11-10:11:00 4, lucene book, 5000, 2008-11-10:11:00, 2008-11-10:11:00 If I will Indexing these datas, they will have a unique docid. And I update one of them that has good_id "1", price colunm 30000 to 35000 and UPDATEDATE colunm 2008-11-10:11:00 to 2008-11-10:12:00. In this case , I want update my index with new data good_id "1". In book, If I want to update my index then I should delete target data from index and add data to index. If the target data is one, I think It is no matter for me, and applications. But if the target datas are over 3000 (or more) , this applcations must do job delete data and add data each 3000(or more) times. I worried about It will be problem to my applications. Or Is this job no matter? I need your helps.. :-) many thanks. Jang. -- DEV용식 http://devyongsik.tistory.com
