problem with regex

[weedlili]

Hello,

I use a regex tested here and there to filter my graph on a quite huge attribute. It works fine on these websites but not on Gephi (nothing is selected when I click on "select").

I chose Filters>Attributes>Equal>My_attribute>, then entered my regex, clicked OK, then SELECT.

Is there a special syntax? Here is my regex: [0-9a-zA-Z. \(\)]+[P|p]hylogen[0-9a-zA-Z. \(\)]+

Thanks,

W.

Ok, seems that the websites I used where not that trustable...
Everything works fine in Gephi too when I use

([0-9a-zA-Z.'\[\]\?\-&;:\ \(\)]+)?(?i)phylogen([0-9a-zA-Z.'\[\]\?\-&;:\ \(\)]+)?

I keep my post online in case it could help someone.

It would be really great if this syntax could be rendered easier. Right now, filtering for strings really isn't trivial, but it's often required.

I think something like

*query* should do the far too complex regex.

There should be an SQL-equivalent LIKE query to find occurrences of a string.
