You will first need to have a database with a timestamp type of column. Once this is in place you can run the wizard to generate the set of pages. When in the wizard just make sure to display the fields that you need to be in place on the search page, don't worry about setting up the search parameters yet. Once the wizard is complete go to the search page and ensure that there are two form fields for entering the dates, if there is only one you can just copy it but make sure to update the name.
You can then go to the results page and edit the DataAssist Search server behavior. In here you will want to add two new criteria. For the first one you will select the date column, for the column type choose date, then select 'greater or equal to' for the comparison. Under the filter select value for the type, then for the value use the lightning bolt icon to select your form field where the first date will be entered.
The second criteria will be almost identical except for the comparison you will choose 'less than equal to' and for the value select the text field where the second date will be entered.
When you do this you can search the table based on a date range. You will need to enter the date in the same format you see it in your db. If you would like to update the format the user can enter the date let us know.
