http://issues.apache.org/bugzilla/show_bug.cgi?id=30330 IndexReader.delete(term) does not delete last doc from TermDocs list ------- Additional Comments From [EMAIL PROTECTED] 2004-07-30 20:59 ------- It is quite possible that there is a problem with how I am adding and then deleting a document from the index which is the source of the problem, although what I am doing is only a small variation on the Demo code. I'm not a Java programmer and have only just recently started playing with Lucene. I've attached two class files which are small modifications to the IndexFiles.java and DeleteFiles.java files included in the lucene distro. I've also included the jar file that includes them (although I received an error when uploading and am not positive it got uploaded safely). I'm afraid I don't have a publicly accessible server where you can see directly what I have, but here's a complete rundown of what I did: - created and archive of plain text/html documents (in this case in the directory /home/acolliso/ archive) - ran java org.apache.lucene.demo.IndexFiles /home/acolliso/archive This created an index of about 190 MB and searching on the index appears to work fine. - then I ran the following: > java org.apache.lucene.demo.IndexFile /home/acolliso/archive/newdoc1.html adding /home/acolliso/archive/newdoc1.html 244 total milliseconds newdoc1.html is a small file with a few unique words in it so I know it will show up at the top of my search later on. Note that IndexFile does *not* run optimize. don't know if that has any consequences. > java org.apache.lucene.demo.SearchFiles Query: +white +dwarfs +black +holes Searching for: +white +dwarfs +black +holes 2 total matching documents 0. /home/acolliso/archive/newdoc.html 1. /home/acolliso/archive/newdoc1.html > java org.apache.lucene.demo.DeleteFile /home/acolliso/archive/newdoc1.html Path to delete: /home/acolliso/archive/newdoc1.html Term: path:/home/acolliso/archive/newdoc1.html Got next doc ...false Term docs: 164437 deleted 0 documents containing path:/home/acolliso/archive/newdoc1.html The 'path' *seems* to be o.k., but next() returns false and the doc is not deleted, as the following search confirms: > java org.apache.lucene.demo.SearchFiles Query: +white +dwarfs +black +holes Searching for: +white +dwarfs +black +holes 2 total matching documents 0. /home/acolliso/archive/newdoc.html 1. /home/acolliso/archive/newdoc1.html The I modified the delete() code as noted in the original report and tried delete() again: > java org.apache.lucene.demo.DeleteFile /home/acolliso/archive/newdoc1.html Path to delete: /home/acolliso/archive/newdoc1.html Term: path:/home/acolliso/archive/newdoc1.html Got next doc ...false Term docs: 164437 deleted 1 documents containing path:/home/acolliso/archive/newdoc1.html And to see if the document really was deleted, I did the search again: > java org.apache.lucene.demo.SearchFiles Query: +white +dwarfs +black +holes Searching for: +white +dwarfs +black +holes 1 total matching documents 0. /home/acolliso/archive/newdoc.html Which makes it seem that the doc was successfully deleted. If there is any other info I can provide that would help, or could provide in a different format, I'm happy to provide it. Or, if this really ought to go to the distro list instead, I'm happy to do that as well.
