I am using SharePoint 2013. I have add a managed metadata site column to multiple document libraries. In the search if I input owstaxidmetadataalltagsinfo:keyword
it will return all items tagged "keyword" tag.
My question is what is the query string to list all items tagged with multiple tags? e.g. owstaxidmetadataalltagsinfo:keywordA AND owstaxidmetadataalltagsinfo:keywordB
Also, it there OOTB feature or sample code to facilitate users to submit above search? So that they don't need to learn the query string.
