Class Method Details

.find(terms = [], options = {}) ⇒ Object

Finds Items in Google Base using the “snippets” Atom feed.

Options:

  • :limit => <Max number of results to return>

  • :offset => <0-based, starting offset of result set>

All other options are passed as structured terms (e.g. part of the ‘bq’ param).

**Options param will be mutated
