Eric, Thanks for your reply. I should have given a better context. I'm currently running an incremental crawl daily on this particular source and indexing the documents. Incremental crawl looks for any change since last crawl date based on the document publish date. But, there's no way for me to know if a document has been deleted. To ensure that, I ran a full crawl on a weekend, which basically re-index the entire content. After the full index is over, I call a purge script, which deletes any content which is more than 24 hour old, based on the indextimestamp field.
The issue with atomic update is that it doesn't alter the indextimstamp field. So even if I run a full crawl with atomic updates, the timestamp will stick to its old value. Unfortunately, I can't rely on another date field coming from the source as they are not consistent. That translates to the fact that I can't remove stale content. Let me know if I'm missing something here. - Thanks, Shamik -- View this message in context: http://lucene.472066.n3.nabble.com/Indexing-question-on-individual-field-update-tp4116605p4116757.html Sent from the Solr - User mailing list archive at Nabble.com.
