Re: insertion time
Hi Mahmoud, I haven't been looking for new DIH featrures, but I don't think there is something that can provides such functionality and that only thing you can do is track it in your source and index it (like createDate and lastUpdatedDate).

Hello, We always update the same document many times using DataImportHandler. Can I add a field for the first time the document inserted to the index and another field for the last time the document updated? Thanks, Mahmoud
Sorting by insertion time
Hi, Quite often I want a set of documents ordered by the time they were inserted, i.e. give me the 5 latest items that matches query foo. I usually solve this by sorting on a date field. I had a chat with Eric Hatcher when he visited Javazone 2009 and he said that Solr places documents on disk in insertion order. This would make it possible for me to save a sorting step by not sorting by a specific field, but by insertion time in reverse. AFAIK Lucene knows how to do this, but which request parameters should I use in Solr? Kind regards, Tarjei -- Tarjei Huse Mobil: 920 63 413
RE: Sorting by insertion time
Hi Tarjei, See https://issues.apache.org/jira/browse/SOLR-1478 - with trunk Solr (and soon, 1.4), you can use pseudo-field _docid_ for this purpose.
