[jira] Assigned: (LUCENE-301) Index Writer constructor flags unclear - and annoying in certain cases
[ http://issues.apache.org/jira/browse/LUCENE-301?page=all ] Michael McCandless reassigned LUCENE-301: - Assignee: Michael McCandless (was: Lucene Developers) Index Writer constructor flags unclear - and annoying in certain cases -- Key: LUCENE-301 URL: http://issues.apache.org/jira/browse/LUCENE-301 Project: Lucene - Java Issue Type: Improvement Components: Index Affects Versions: 1.4 Environment: Operating System: other Platform: Other Reporter: Dan Armbrust Assigned To: Michael McCandless Priority: Minor Wouldn't it make more sense if the constructor for the IndexWriter always created an index if it doesn't exist - and the boolean parameter should be clear (instead of create) So instead of this (from javadoc): IndexWriter public IndexWriter(Directory d, Analyzer a, boolean create) throws IOException Constructs an IndexWriter for the index in d. Text will be analyzed with a. If create is true, then a new, empty index will be created in d, replacing the index already there, if any. Parameters: d - the index directory a - the analyzer to use create - true to create the index or overwrite the existing one; false to append to the existing index Throws: IOException - if the directory cannot be read/written to, or if it does not exist, and create is false We would have this: IndexWriter public IndexWriter(Directory d, Analyzer a, boolean clear) throws IOException Constructs an IndexWriter for the index in d. Text will be analyzed with a. If clear is true, and a index exists at location d, then it will be erased, and a new, empty index will be created in d. Parameters: d - the index directory a - the analyzer to use clear - true to overwrite the existing one; false to append to the existing index Throws: IOException - if the directory cannot be read/written to, or if it does not exist. Its current behavior is kind of annoying, because I have an app that should never clear an existing index, it should always append. So I want create set to false. But when I am starting a brand new index, then I have to change the create flag to keep it from throwing an exception... I guess for now I will have to write code to check if a index actually has content yet, and if it doesn't, change the flag on the fly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
