The sample will show you how to get data with multiplevalues Field in a site collection.Many users want to get data with multiple value fields (user-multi field, taxonomy field and so on) in site collection. In general,we can achieve it by using SPSiteDataQuery; however, the value of the multiple value fields will be empty.For this requirement, we can consider SQL syntax search query, like FullTextSqlQuery.
