OrientDB：如何使用其他顶点的数据更新字段

Question

I'm working with some document trying to implement the TF-IDF method to search similarities over documents. At one point, I need to calculate the Term Frequency (TF). I have two vertex in this realation: Documento ---> DocWord

DocWord vertex has the following fields: int frequence double tf double idf

Documento has: int wordCount

I need to update all DocWord tf field with: frequence/Documento.wordCount

The query I'm trying to run is:

update DocWord set tf = frequence/in("Documento_docwords").wordCount[0];

but this fail.

Answer 1

尝试：

update DocWord set tf = (frequence / in("Documento_docwords").wordCount[0])
