我试图将termFreq()
函数与短语一起使用,例如
termfreq(field, "cool phrase")
我使用shingleFilter
,以便它可以对单词进行分组,并像单个术语一样查找结果。当我像这样使用它时:
termfreq(field,phrase)
单词"短语"将由为该字段注入的所有过滤器处理,例如
stemming
lowercase
stopwords
当我使用短语时,除非我指定确切的术语,否则它不起作用。一个例子是:
termFreq(field, "cool phrase") -> x
termFreq(field, "cooL PHRASE") -> y
是个错误吗?
