 Currently the `s` parameter in WP_Query is hardcoded to only search in the
 `post_title` and `post_content` fields. A decent enhancement would be if
 you could also specify which postmeta fields it can search into as well.

 Also allowing more fine-grained control so that it can search only
 postmeta fields and ignore `post_title` and `post_content` as well.

 Something along the lines of:
 {{{
 's'             => 'foo',
 's_fields'      =>'title',
 's_meta_fields' => array( 'custom_field_1', 'custom_field_2' ),
 }}}

 `s_fields` can a string/array of either post_title and/or post_content.
 Setting it to false would disable searching these fields and assume you
 have set custom meta fields to search for instead. By default it would be
 `array( 'title', 'content' )`.
 `s_meta_fields` can accept a string/array of postmeta field names to
 search for. By default it would be `false`.

 A decent use case would be the [https://wordpress.org/plugins/search-by-
 sku-for-woocommerce/ Search by SKU for Woocommerce] plugin which resorts
 to writing a custom query.

 I assume the only real concern would be performance.
