Hi,

I have been using SWISH::API happily to search three individual indexes. 
Now I want to search all of them at the same time, as specified in the 
SWISH::API documentation. However, when passing the index files as a space 
separated string, I get the following error message:

err: Index Header Error: Index file 
'd:/website2/cgi-bin/search/index/pmr/nostem.idx 
d:/website2/cgi-bin/search/index/prb/nostem.idx 
d:/website2/cgi-bin/search/index/manuals/nostem.idx' is not an active 
index file
.

The three individual indexes exist and can be searched without a problem.

Can someone shed more light on what exactly this error message means and 
what I might be doing wrong?

Thank you, Jonas.
