如何解决在下面的json代码段中出现“错误”类型的警告，我们看到“成功”：1`

在我们的wikibase server上，我们看到一条神秘的消息，即“错误”类型的警告，而在下面的json代码段中，我们看到了"success": 1

Warning: {"type":"error","message":"cirrussearch-backend-error","params":[]} [Called from Wikibase\Search\Elastic\EntitySearchElastic::getRankedSearchResults in /var/www/html/extensions/WikibaseCirrusSearch/src/EntitySearchElastic.PHP at line 318] in /var/www/html/includes/debug/MWDebug.PHP on line 333

解决方法

CirrusSearch README提到了一些似乎有所帮助的步骤：

Now run this script to generate your elasticsearch index:
 php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/UpdateSearchIndexConfig.php
Now remove $wgDisableSearchUpdate = true from LocalSettings.php.  Updates should start heading to Elasticsearch.
Next bootstrap the search index by running:
 php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/ForceSearchIndex.php --skipLinks --indexOnSkip
 php $MW_INSTALL_PATH/extensions/CirrusSearch/maintenance/ForceSearchIndex.php --skipParse
Note that this can take some time.  For large wikis read "Bootstrapping large wikis" below.
