我有两个数据源
DataSourceA(id,keyword)和DataSourceB(pid,pdftext)
我如何从DataSourceA获取具有Keyword = Radiology的文档或其在DataSourceB中的匹配文档在其pdftext中具有Radiology。
换句话说,作为sql语句
Select A.* from DataSourceA As A inner join DataSourceB As B on A.id=B.pid where A.keyword='Radiology' OR B.pdftext='Radiology'
我试过了
fq = {!join from = pid to = id} pdftext:Radiology OR Keyword:Radiology
但这没有用......任何想法?
