   Hi,
   I'm using the Co Author plus plugin,
   and I can't figure out how to retrieve all the posts by one (co) author knowing the plugin is using taxonomies.
   Any tips? thanks.

   WP_Query is your friend. Something like this should work:

   $author_posts = new WP_Query( array( 'author' => $author_login ) );

   I tried that,
   it does not work : my query is to retrieve my author posts in a certain category, it retreives me all the posts of that category, ignoring the author.

   In that case, you'll want to use a tax query to query multiple taxonomies.

   Ok,
   could you be more specific?
   As i see in the WP_Query example :
   

   $args = array(
   	'tax_query' => array(
   		array(
   			'taxonomy' => 'people',
   			'field' => 'slug',
   			'terms' => 'bob'
   		)
   	)
   );

   In the case of the co authors, what taxonomy am I supposed to use?
   Same question for the 'field' parameter.
   I suppose i have to put my user_login for the 'terms' parameter.

   To have a more specific example :
   I have to retrive all the posts, in the category 'news' from my author 'john-smith' (who is a secondary author thanks to the co author plugin, not the primary one)

   Something like this should work:

   $args = array(
   	'tax_query' => array(
   		array(
   			'taxonomy' => 'category',
   			'field' => 'slug',
   			'terms' => 'news'
   		),
   		array(
   			'taxonomy' => 'author',
   			'field' => 'slug',
   			'terms' => 'john-smith'
   		)
   	)
   );
