[CSCMail-Users] Filters problem ...

[Laurent M. <lau...@se...>]

Hello,

I've got a little problem with one of my filter ....

Here the filter:
   Génération	      Nom
   Subject Base      Type
   Generation	      Move to Folder

   Gen (AR|BL|NE|ZH|cre|pre)   search expression.

Only message with 

    'Gen AR '
    'Gen BL '
    'Gen NE '
    'Gen ZH '

are moved to the folder 'Generation' but message with

    'Gen cre1_0 '    (With no space between 'cre' & '1_0')
    'Gen pre1_1 '

are not , but
     'Gen cre 1_0'   (with a space between 'cre' & '1_0')

is moved to the folder ....

Is it a normal feature ?
If yes, How can I filter messages with only part of a word and not
a complete word ? (i.e message coutaining 

Gen (AR|BL|NE|ZH|cre[a-z_A-Z0-9]*|pre[a-zA-Z_0-9]*)

Thank you very much
