Search and return conversion value from elastic search

[kyungmin]

As a part of the dashboard changes (https://github.com/balanced/balanced-dashboard/issues/1085#issuecomment-41117842), we need to surface international currency to the search results page, like:

To do so, we need the following backend changes:

• [ ] Return amount_in_captured_currency in addition to amount
• [ ] Search for both amount and amount_in_captured_currency (e.g. searching for 10.00 returns USD and EUR if both exists)

When can this be done by?
