Searching by a custom languages tags

[Yuri-Chud]

Hello, @lonvia!
I want to make search a data by language tag alt_name.
My first question is here.

I downloaded realize 0.4.3 and tried to import using this command by passing the -language with alt_name argument (also tried without it):
java -jar photon-*.jar -user_name -port -local host -port 5432 -database name -username -password mysecretpassword -languages alt_name

But my search query can't find the names that exist in these special language tag (but I can get result from default languages (e.g. from en)).
Do I need to write additional commands to make the search by these tags ("alt_name") too?
