Yes and the value is "true". I noticed that data instances have not been indexed. I click re-index but still it does not work. There must be 30000+ instances. But the number of documents is 1700 in search landing page.
I do not see any sql query in the tracer. And pySearchResultsData page is empty. I think it is because of the data indexes. As I said in my above comment, the number of documents for data indexes should be 30000+. But there is just 1700.
