Alter Acquia Search Results I am using acquia search on D7 site. By default I get all the search results as Title, Teaser with search info at the bottom. I am trying to alter this results to add some of the field data.

Eg: Content type is a product and there is a Date of arrival field and Stock availability field for all the Product node.

Now how can I add these two fields as part of every result on search results page?
You can use hook_apachesolr_query_alter($query) to alter your results variable, if you're using Apache solr views and this error

Notice: Undefined property: apachesolr_views_query::$group_operator in apachesolr_views_query-&gt;build() (line 80 of /var/www/html/root/sites/all/modules/apachesolr_views/apachesolr_views_query.inc‌​).

this means that you didn't use filters in your view.
