If you do:

swish-e -f yourindex -T index_metanames

you can see this:

swishfilenum : id= 4 type=42  META_INTERNAL META_PROP:NUMBER

in a search, the property 'swishfilenum' is available like any other 
property:

swish-e -f myindex -w foo -x '<swishfilenum>\n'

# SWISH format: 2.4.1
# Search words: foo
# Removed stopwords:
# Number of hits: 13
# Search time: 0.046 seconds
# Run time: 0.141 seconds

.

With SWISH::API I think you use the $result->Propery( "swishfilenum" ) 
method.

That's only one way to access the filenum (returning it as a property) 
and it only works after you've searched. If you wanted to know the 
filenum *before* searching, use this:

swish-e -f myindex -T index_files

and then parse that out to a db or file or whatever.

Hope that helps.
