Add Language Support for Search Results

[jboarman]

The current hl language option refers to the language of the HTML UI. However, to search for results in a particular language, the lr parameter must be set.

Please add support for both language options:

• hl => HTML Language (UI)
• lr => Language of Results (Linked Content)
