You need a Moodle site that is set up to work with Moodle global search using Apache Solr, Simple Search or another search engine. (to be enabled @ admin -> plugins -> search. It will make this test quicker if your site does not have much content. (I.e. if it only takes a couple of minutes to index everything.) Go to the search areas page in the site administration menu ( Plugins / Search / Search areas ) Click Update indexed contents . EXPECTED: A confirmation prompt should appear. Click Cancel EXPECTED: You get back to the search areas page. Click Update indexed contents and, this time, Continue . EXPECTED: The search index should be updated (this may be slow if you have added a a lot of content since it was last updated, and there is no indication of any progress). You should get back to the search areas page with a Search engine contents have been updated notification message. Click Delete all site contents . EXPECTED: You should see a confirm prompt. Click Continue . EXPECTED: After a short time you should be returned to the search areas page with a notification All indexed contents have been deleted . Each search area should show Never for its last indexed time. Click Reindex all site contents . EXPECTED: You should see a confirm prompt. Click Continue . EXPECTED: The search index will be recreated (this will be slow if your site contains significant content; on my test site it takes about 15 minutes, during which there is no indication of any progress). You should get back to the search areas page with a notification All site contents have been reindexed . The search areas should now show last-update dates again. Next to one of the search areas that contains content, click Delete index . EXPECTED: You should see a confirm prompt. Click Continue . EXPECTED: After a short time you should be returned to the search areas page with a notification Index deleted . That search area should be marked as Never updated. Click the Disable (eye) link next to a search area. EXPECTED: You should get back to the search areas page and the area should be marked as disabled, with a notification Search area disabled . The URL should be the plain searchareas.php and should not include other parameters such as action=disable. Click the Enable (eye) link next to the disabled area. EXPECTED: You should get back to the search areas page and the area should be marked as enabled, with a notification Search area enabled . The URL should be the plain searchareas.php and should not include other parameters such as action=enable.
