Ignore Case   

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", etc. 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.

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.
