/expand with langs filter doesn't work

[jtara1]

Is this intended to be a filter? Comparing it to node-postal, I believe node-postal filters out others entirely.

example:
ca is ambiguous

curl --silent -X POST -d '{ "query": "200 main blvd, los angeles, ca, usa", "langs": ["en"] }' http://localhost:8080  | jq

expands to

[
  "200 main boulevard los angeles coahuila usa",
  "200 main boulevard los angeles compania usa",
  "200 main boulevard los angeles compania anonima usa",
  "200 main boulevard los angeles calle usa",
  "200 main boulevard los angeles ca usa",
  "200 main boulevard los angeles california usa"
