Keeping track of modifications will have to occur outside of Lucene. What you could do is check the file's metadata, particularly creation date or modification date, and only index (or reindex) files based on these values.
For example: 1. Created today: Fresh index 2. Created yesterday, modified today: reindex 3. Created yesterday, modified yesterday: no indexing needed -----Original Message----- From: raygrrr [mailto:[email protected]] Sent: Sunday, July 31, 2011 10:53 PM To: [email protected] Subject: RE: indexing question, please have a look :) Thanks Jason, my basic need is to search for Date and Time ranges of files. For instance, I'd like to find all files on my local file system which were modified in April 2011. My concern is that I don't know what files are new or modified when indexing a directory. Many thanks for your help! -- View this message in context: http://lucene.472066.n3.nabble.com/indexing-question-please-have-a-look- tp3209149p3214763.html Sent from the Lucene - General mailing list archive at Nabble.com.
