Multiple countries of origin for filtering accessions

When trying to filter accessions by multiple orgCty, when writing the first orgCty the system gives an autocomplete recommendation (with the country ISO3). But, when I try to add more countries, the autocomplete function disappears.

To replicate:

• Go to https://sandbox.genesys-pgr.org/explore
• Try to apply the Country of Origin filter for two different countries

Additional Info

When making the autocomplete call to the server, the field we are autocompleting (e.g. orgCty) must be excluded before the query to ES or the database.
