Ranges include their endpoints. Ranges can also be used with strings as well as numbers. Ranges can also be one sided. A filter can contain a list of single values and ranges. The values in the list should be enclosed in parentheses.
Filters can test more than one column in a table.
The individual tests are separated by commas or semicolons. All tests in the filter must succeed for the filter to be accepted. A range of row numbers can also be selected by placing the word row on the left side of the equals sign. Row selection can be combined with any other test in a filter. Include files can be a part of a larger expression and include files can contain other files, up to seven levels deep.
