NCBI esearch on multiple database

Question

[peteladrien]

I'm currently using the NCBI esearch API to fetch informations on several organism.

The URL looks like

esearch.fcgi?db=database&term=query

where db is the database used for the query. Is it possible to pass severals databases instead of one?

for example, the query would look like

esearch.fcgi?db=protein,nucleotide&term=query
