Keeping query index until a complete reindex is done

[Silvio Hermann]

Hi there



is solr capable of keeping a query index until a complete reindex is done (within a single core)?

I think something of:

1. start reindex/rebuild through a REST push (not the data import handler)

2. solr starts indexing on a fresh index

queries are handled by the old index

3. with a SWAP or simmilar command the old index is dropped and all query/index stuff is handled

by the new index



Thanks in advance

Hi,

Yes. Two alternatives

1) If you just want to reindex, no big schema changes etc
Just reindex everything on top of the old index.
Search will still be live all the time

2) Create a new core/collection
Reindex everything to that collection
Use the SWAP core admin command when finished
http://wiki.apache.org/solr/CoreAdmin
Unload/delete the old index
