Hi As I understand, even if I use partial update, lucene can't really update documents. Solr will use the stored fields in order to pass the values to lucene, and a delete,add opeartions will still be performed.
If this is the case is there a performance issue when comparing partial update to full update? My documents have dozens of fields, most of them are not stored. I sometimes need to go through a portion of the documents and modify a single field. What I do right now is deleting the portion I want to update, and adding them with the updated field. This of course takes a lot of time (I'm talking about ten of millions of documents). Should I move to using partial update? will it improve the indexing time at all? will it improve the indexing time in such extent that I would better be storing the fields I don't need stored just for the partial update feature? thanks -- View this message in context: http://lucene.472066.n3.nabble.com/Partial-update-vs-full-update-performance-tp4069948.html Sent from the Solr - User mailing list archive at Nabble.com.
