Django的草堆+ ElasticSearch儀

Question

所以基本上我試圖分析儀添加到我的草堆後端Elasticsearch和到目前爲止，我還沒有運氣。

我想查詢像這樣3/09.0TBOBR.C1，我也得到很多的錯誤。有人告訴我分析是解決我的問題，所以我嘗試使用keyword分析

我想是這樣的：

class ConfigurableElasticBackend(ElasticsearchSearchBackend): 

    DEFAULT_ANALYZER = "keyword" 

，我也試過這樣在我的設置文件：

ELASTICSEARCH_DEFAULT_ANALYZER = "keyword" 

我做了重建索引更改後

我的錯誤消息是：

Failed to query Elasticsearch using '(3/09.0TBOBR.C1)': 
Non-OK response returned (400): 
    u'SearchPhaseExecutionException[Failed to execute phase [query], all shards failed;

我到底做錯了什麼？感謝

Answer 1

與草垛查詢方的問題是，它使用document=True在您的搜索索引配置標記包羅萬象的領域。該字段很可能沒有使用關鍵字分析器進行分析。但你最好檢查通過查看elasticsearch的輸出（此列出的分析儀）：

http://localhost:9200/<index-name>/?pretty=true 

在堆棧跟蹤你可以看到：

「default_field」：「文本」

你不妨考慮一下有兩個不同的搜索看法，如果你仍然想支持自由文本用戶搜索與「正常」的輸入。對於像3/09.0TBOBR.C1這樣的輸入的特殊搜索，您可能需要使用Haystack的SearchQuerySet的.filter()或.narrow()方法，您可以在其中指定要搜索的字段（並且這將是明確使用keyword分析儀的字段）。對於常規文本字段，您可能不想使用關鍵字（==否）分析。
