I just tried all possible combinations of index files, and it turns out 
that all individual indexes work fine, and any pair (or the triple) gives 
the same error message. So it is not one 'faulty' index, it must be 
something general.

SWISH::API


mine was just a copy/paste from the SWISH::API man page with a little 
tweak to let me run it from the cmd line:

my $indx = shift @ARGV;
my $swish = SWISH::API->new( $indx );
$swish->AbortLastError
         if $swish->Error;


I called it like:

swishtest '/path/index1 /path/index2' -w test

and it searched both indexes just fine.

Have you tried different combinations to see if there's one index in 
particular that causes the failure?
