Sphinx Indexer not working

[mgoetze]

I'm about 90% through the install process with Sphinx on my Linux server running VB5. My vbulletin database name is vbdb. When I run the indexer --all command I get the following error:

[root@www sphinx]# indexer --all

using config file '/etc/sphinx/sphinx.conf'...
indexing index 'test1'...
ERROR: index 'test1': sql_query: Table 'vbdb.documents' doesn't exist (DSN=mysql://vbadmin:***@localhost:3306/vbdb).

anyone have an idea what I am doing wrong? it appears to be looking for a table named documents, which we dont have in VB5..
