I just added the new version of Global Site Search to my production multi-site installation and updated the Post Indexer plug-in to the latest version.
When I search, the results do not include the href values for posts that it finds (see http://blogs.american.edu and search for "kitchen" as an example). Upon further investigation, it appears there is a problem with the latest version of Post Indexer, specifically the network_get_permalink function. Version 188.8.131.52 of Post Indexer works correctly.
