I have been trying to plan out a history function for Solr. When I update a document with an existing unique key, I would like the older version to stay around and get tagged with the date and some metadata to indicate it's not "live." Any normal search would not touch history documents.
Interesting... One might be able to accomplish this with the update processors that Ryan & I have been batting around for the last few days, in conjunction with updateable documents, which is on-deck. The first idea that comes to mind is that during an update, you could change the id of the older document to be something like id_<timestamp>, and reindex it with the addition of a live:false field. For normal queries, use a filter of -live:false filter. For all old of a document, use a prefix query id:mydocid_* for all versions of a document, use query id:mydocid* So if you can hold off a little bit, you shouldn't need a custom query handler. This will be a good use case to ensure that our request processors and updateable documents are powerful enough. -Yonik
