Please rename the issue:
Allow to use one field in filters multiple times
I don't have permission for that
I think it's more common issue and can be resolved in another way.
Need to allow to filter one field several times.
For example:
filtering field "date" type
Now possible values are:
is less than
is more than
in
today
this week
less than days ago
more than days ago
days ago
It's not easy.
more easy values are:
is less than
is more than
less than days ago
more than days ago
But allow to filter this field two times.
For example to get "today" variant i need two filters:
less than days ago = 0
more than days ago = 0
to get "this week" field i need two filters:
less than days ago = 0
more than days ago = 7
Of corse it allow to find issues with two words in the subject: for example date & filter
I can write patch if you are agree to insert this feature in the redmine
