Thierry, If you always start from scratch you could even reset the index completely (i.e. delete the index directory). Solr will create a new index automatically at startup. If you don't like to delete the files another approach would be to use a query that returns all documents. You do not need a dummy field for this. The range query [* TO *] returns all documents. (In newer versions of solr you can use *:* which is executing a bit faster.

So delete all, than add all. To use the delete all, we did the following. We added a field called dummyDelete. This field always contains the value delete. Like this <field name="dummyDelete">delete</field> Then to delete all documents we do a request containing: <delete><query>dummyDelete:delete</query></delete> That way all documents are deleted where the field dummyDelete contains delete => all the documents Hope this is clear. I am not sure if this is a good solution, but it does work. :) Greet, Thierry On 25/05/07, Jack L <[EMAIL PROTECTED]> wrote: > > Oh, is that the case?
