Just to be clear, [* TO *] does not necessarily return all
documents. It returns all documents that have a value in the
specified (or default) field. Be careful with that! *:*, however,
does match all documents.

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.

Betreff: Re: Re[2]: add and delete docs at same time
We always do a full delete before indexing, this is because for us
that is the only way to be sure that there are no documents in the
index that don't exist anymore.
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. :)

Oh, is that the case? One document per request for delete?
I'm about to implement delete. Just want to confirm.

currently no.
Right now you even need a new request for each delete...

Some thing like this:
myDocs.xml
=====================================
<add>
<doc><field name="mainId">4</field></doc> <doc><field
name="mainId">5</field></doc> <doc><field
name="mainId">6</field></doc> </add> <delete><id>1</id></delete>
<delete><id>2</id></delete> <delete><id>3</id></delete>
=====================================
Thanks!
