 ==== Which Vaadin UI version is included? ====
 We use the latest [[https://sourceforge.net/projects/jvx/files/vaadin%20UI/|Vaadin UI]] based on Vaadin 8.1.6. The system requirements for Vaadin 8.1.6 can be found [[https://vaadin.com/download/release/8.1/8.1.6/release-notes.html#supportedversions|here]].
+==== When dragging a table into a screen...Do you query all records ====
+We have lazy loading everywhere and per default we only load the records that you see on the screen and some more to fill a buffer. We usually load records for about 100 milliseconds but at least the visible amount. The scrollbar shows that more rows are there. When you scroll down, more rows are loaded. The speed depends on the database query/performance and network speed.
+==== Is it possible to search based on 2 or more columns (but not all columns) ====
+No problem, just drag another search field from the bottom of the screen. Choose a column and condition (equal, smaller, ...) for each field. All of them will be combined with an AND. A search field without specific condition will act as full-text search for "all columns".
