taxonomy search for multiple species simultaneously

[molsim]

In advanced filter it is good to have the opportunity to enter several taxonomic names separated by comma.
Currently, "drosophila, gallus" finds nothing, whereas if you search for them separately everything works.

Did you use the "in" search type?

Would it be better to:

1. automically use the "in" option if there is a comma? Same for simple search?
2. Have +/- buttons to add an extra field (Definitely easiest for user understand, but may take up lots of space and take longer to write)
