	The Indicates the value entered is an expression. Click this icon to change this, if you want to enter switch the value to a literal value.
Ignore CaseThe condition matches values ignoring case e.g. "abc" would match	Insert excerpt _check_box_untick _check_box_untick nopanel true so that, for PhixFlow instances running on Oracle or MariaDB (MySQL), the condition only matches strings that have the same capitalisation (case-sensitive). Insert excerpt _check_box_ticked _check_box_ticked nopanel true   so that the condition matches strings that have any capitalisation (case-insensitive). For example "abc" matches "abc", "Abc", "ABC", etc. The default setting is defined on the underlying Stream Attribute  For case-insensitive filters, there is no difference if the attribute is also indexed.  Whether or not the check box is ticked by default depends on the underlying stream attribute property tab → Advanced section → Filter conditions are case-independent by default. Note This option affects the behaviour of filters for PhixFlow instances running on Oracle or MariaDB (MySQL) databases. For PhixFlow instances running on a SQLServer database, filters are always case-independent.
Insert excerpt _filter_picker _filter_picker nopanel true	Display the filter picker. Click this icon to display a list of possible values to filter by. See Filter1261699659, below.

Some Filter Examples

Create prompt filter

You can create a filter that will prompt users to enter a value, and filter based on that. For example, if you have data which contains people's names, you could create a filter like:

Name contains _prompt.EnterName fx

Filter on Current User

If your data contains details of the user, you may be able to filter based on the currently logged in user. For example, to set a filter where the owner equals the current logged in user, add a condition to the filter:

Owner equals _user.name fx

Enter a list of values for an "Is In" or "Is Not In" filter

If you want to select a set of records which have a field set to one of a range of possible values you can do this by selecting the "Is in" or "Is not in" comparator from the drop down list and then simply typing the list of values into the edit box to the right of the comparator as a comma separated list like this:

Country Is in England, France, Germany ABC

Alternatively, you can enter the comparison value as expression:

Country Is in ["England","France","Germany"] fx
