Gem forces the use of q parameter for engines that is not used #10
Description
We have several engines that work without a q parameter.
For example, Yande uses text:
And you can't submit your search to the API.
Hash with all engines that don't use q parameter:
{
ebay: '_nkw',
google_maps_reviews: 'data_id',
google_product: 'product_id',
google_scholar_author: 'author_id',
google_scholar_profiles: 'mauthors',
home_depot_product: 'product_id',
walmart: 'query',
walmart_product: 'product_id',
yahoo: 'p',
yandex: 'text',
youtube: 'search_query',
naver: 'query',
apple_app_store: 'term',
apple_reviews: 'product_id',
yahoo_shopping: 'p',
google_play_product: 'product_id',
}We can explicitly check on this but I think it will easier to just drop the requirement of a q parameter for all engines.
