Many thanks for jumping in Xavier. I was in the cinema with my son the last
3 hours so couldn't answer here.
@Jon: You need to know that there is no numerical comparrison in filter
expressions. So what I do is a "text match".
There are some special characters in these matches.
Examples
"." matches any character (like ? in DOS)
"^" means that the string to compare to needs to start here
"$" means that the sttring needs to end here
Format of a date is: YYYYMMDDhhmmssxxx
Example for a date: 20140302165811567 for 2014-03-02 16:58:11.567
Matching any date: ^.................$
Matching any 2014 date: ^2014.............$ can be shortened to ^2014
Matching any March: ^....03...........$ can be shortened to ^....03
Matching any 1st of month: ^......01.........$ can be shortened to ^......01
"|" seperates 2 alternatives and
"(" ")" groups parts so
^(2013|2014) matches anything starting with 2013 or 2014
Now why would this ^201(3|4) also match 2013 and 2014?
Then there are "character classes" written as "[clasmembers]" where the
full class matches if one of the characters of the class is at that
position. So
^201[34] will also match 2013 and 2014
I think this is enough for know, okay?
