* Now, trying to index, i’m getting this error (updated to WPSolr 4.0):
* ```
Notice: Undefined variable: res_final in /Applications/MAMP/htdocs/bedrock/web/app/plugins/wpsolr-search-engine/class-wp-solr.php on line 828
{"nb_results":0,"status":0,"indexing_complete":true,"debug_text":null}
Notice: ob_flush(): failed to flush buffer. No buffer to flush in /Applications/MAMP/htdocs/bedrock/web/app/plugins/wpsolr-search-engine/ajax_solr_services.php on line 393
```
* Any idea what could generate this?
NOTE: i have 3 documents/posts and they all
look indexed (so it might be working)

* Also…the search does not work.
* After searching something from the search field…i get this in the console:
* ```
Notice: Undefined index: self_hosted in /Applications/MAMP/htdocs/bedrock/web/app/plugins/wpsolr-search-engine/autocomplete.php on line 20
