#230383  Node access patch by pwolanin:  Backported to 5.x-1.x, fixed indexing of attachment contents.  Tested with organic groups and private content between multiple groups/users, with both node body and attachment content.  Also tested that all content is returned regarldess of permissions when apachesolr_node_access is turned off and the index rebuilt.

upgraded to handle multisite and ->url changes. Also added a hook for modifying documents as they are created

Added the apachesolr_modify_query hook to allow other modules to make changes to the query before sending

Unifying communication with Luke handler. Using wt=json instead of XML/XPath. No longer guaranteed to work with Solr 1.2 (see project page for notes on this decision)

Then make another block that recommends based on author+taxonomy terms. This commit pertains to #304388 and #230375
