Regular expression
Allows you to use regular expressions in the filter definition. For a list of the regular expressions that LibreOffice supports, click here.
If the Regular Expressions check box is selected, you can use regular expressions in the Value field if the Condition list box is set to '=' EQUAL or '<>' UNEQUAL. This also applies to the respective cells that you reference for an advanced filter.
The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every regular expression metacharacter or operator with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in .
When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".
No duplication
Excludes duplicate rows in the list of filtered data.
Keep filter criteria
Select the Copy results to check box, and then specify the destination range where you want to display the filtered data. If this box is checked, the destination range remains linked to the source range. You must have defined the source range under Data - Define range as a database range. Following this, you can reapply the defined filter at any time as follows: click into the source range, then choose Data - Refresh Range.
Data range
Displays the cell range or the name of the cell range that you want to filter.
