To change which patient details you can see in the result items (after a query search), select the "Result Table" tab. Click items to tick/untick them. Ticking an item will create a column in the search results.
Note: you can change the columns before OR after you have searched the query.
To narrow down your search results, use the filter.
To filter the results of any column, hover the mouse over the blue highlighted line. Click on the field to enter the text, or select the field from the drop-down menu. You can control how results are filtered by clicking on the small blue box to the left of the filter field, and choosing from the drop-down menu. To turn off the filter, click on the small symbol of the filter with a cross through it (to the right of the filter field).
