Solr建議與ContextField：不是所有的對象都有該字段

Question

所以我有一個數據庫在索引索引，我試圖過濾搜索建議（建議）使用ContextField/cfq。我想要做的是將建議查詢過濾到上下文字段（布爾字段）設置爲false或沒有該字段的元素。只使用false不起作用，我不確定如何在solrconfig.xml裏的suggest.cfq字段裏表達它，因爲這個字段已經被聲明爲一個contextfield，它看起來並不像我能做的（-myfield：[* TO *] AND ：）或myfield ：假。如何做我想做的事？

solrconfig.xml中的相關大塊：

希望它可以幫助別人。

在提示組件中指定contextField（您的情況爲pieceSuggestsuggester）。 對於<str name="contextField">hidden</str>變化requestHandler的cfq字段值：

<str name="suggest.cfq">-true</str> 

應該提供具有false或沒有hidden領域的價值的所有建議域
