Document WP_Query orderby=relevance

[jnylen0]

I expected relevance to show up here - ​https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters

There may be other parameters/values that are also missing from the WP_Query documentation.

Also need to note that the default orderby changes from date to relevance when a search parameter is passed to WP_Query.

Added 'relevance','type' to document in class-wp-query.php

Please ignore 39336.2.patch

Please ignore 39336.2 patch and consider the 39336.3

Thanks for the patch, @dots.

$relevance should not have its own top-level @param entry, as it's only a possible value for 'orderby'. Your patch also added an entry for $type, but as far as I can see, this is not a valid orderby parameter for WP_Query. Can you have a look at 39336.4.patch​ and see if it matches with your understanding?

@boonebgorges Thanks for the correction. Now, I understand.
