Hi 1. as I understand Lucene is preparing the documents of the search result in a lazy fashion- using the docId in the ScoreDoc. What happens if the document "pointed" by the ScoreDoc is deleted meanwhile i.e. the DocId is not relevant (maybe assigned to a different document) ? 2. when a document is added to an index- (addDocument) I guess there is a period in which the fields are added to the index one by one. What prevents an indexsearcher (esp' in NRT mode) to see "half" document , i.e is it atomic and how? 3 The way to update doc is remove the old and add the updated. Isnt there a problem of a "hole" between the remove & the addDocument in which no document exists , i.e is it atomic and how? 4 is it possible to store a field in the lucene index without indexing it ? (i.e. just gettng it back in the result docs)
Thanks, Yechiel
