Ignore CaseThe condition matches values ignoring case e.g. "abc" would match

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
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
nopaneltrue
  so that the condition matches strings that have any capitalisation (case-insensitive). For example "abc" matches "abc", "Abc", "ABC", etcFor case-insensitive filters, there is no difference if the attribute is also indexed.

The default setting is defined on the underlying Stream Attribute

 

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.
