Have you tried nesting lookups using the "string2" item i.e. the one that
gets used if the lookup fails?
Like
${lookup mysql {select this from that where here =
there}{$value}{${lookup{$there}lsearch{/etc/file}{$value}}}}
I can't say from experience that this will work under the case where mysql
is not available, but I use something like this where the result of the
first MySQL lookup is not found to do a second lookup in another table.
