Exposed search filters, facets, blocks, and AJAX with Apache Solr Search module

In the current Drupal version, views exposed filters, such as search results and blocks with facets, must not have caching enabled alongside AJAX, as the views AJAX request does not pass along the ?f[0]= parameters used by exposed filters or facets to filter results as expected. The open issue on Drupal.org, AJAX facet block seems to lose views context, will be updated as the community identifies fixes and workarounds.
