If I replace flowers with skyblue I get a response with number of search results. But I want a response for "sky blue"
I tried using q=sky%22blue and sky+blue, I am getting errors. How to query with multiple keywords?
The space needs to be escaped with a backslash:
q=sky\ blue
Here is a similar question about escaping characters that may help: http://productforums.google.com/forum/#!topic/commerce-search/sxo5NQ5iAI0
