BUGS

NCBI error 803/temporarily unavailable

As of November 2008, the NCBI/PubMed servers have been a bit unpredictable in returning results to queries issued by W::S::PubMedLite. The only queries that appear to be failing are those that request the PubMed Central ID; for example:

            

              
              
L<http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=16402093&db=pmc>
            
          

The error returned by NCBI is "error 803/temporarily unavailable", which prevents WWW::Search::PubMedLite from filling the pmc_id field in results.

This impacts make test; specifically, if this error is encountered, the "pmc_id" test will be skipped and a brief explanation will be given. It should be safe to continue with the installation provided that the other tests are working. Again, it appears that this problem is confined to the pmc_id field.
