Hello everybody. I have a big index that will be stored in the FS. I have lots of updates, insertions and deletions in the index, and I would like to minimize the number of "phatom reads".
I ve seen in the wiki this link: http://wiki.apache.org/jakarta-lucene/UpdatingAnIndex So, what about my idea: - A singleton SearchEngine - SearchEngine has a IndexReader attribute, and _no_ index writer. - When inserting a new Document, open a writer, writes, close and the replace the old reader for a new one. - When deleting, open a reader, delete, replace the older reader for this opened reader. - The update method deletes than inserts. - When searching, use the attribute IndexReader Now some questions: Is it too bad to open/close a writer every time I write on the index? What about opening a new IndexReader for each new search, instead of keeping the IndexReader attribute? Would it be a lot better to batch updates? I could have a stack of documents to be updated, and I would only write to the indexes when the documentsToBeUpdated.size() reaches a certain number. thanks a lot. -- Paulo Silveira http://www.paulo.com.br/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
