Enable search for bonds

[mkitzmann]

Per default bonds are not searched in the eod search api.
We should therefore probably add a type selector for the searchbar, so the user can select between these types (According to the eod docs):

type: String. OPTIONAL. The default value is ‘all’. You can specify the type of asset you search for.

Possible values: all, stock, etf, fund, bonds, index, commodity, crypto.
Please note: with the value ‘all’ bonds will not be displayed, you should explicitly request bonds.
