Problem using a comma in a Google Analytics API filter

I am having an issue with the Google Analytics Query Explorer when I try to provide a filter with a regexp that contains a comma. I 开发者_如何转开发know that commas must be escaped, but even if I add a blackslash before in the explorer, it does not work.

Example of working filter : ga:pagePath=~^/boutique-p\d{4}

Example of NOT working filter : ga:pagePath=~^/boutique-p\d{1,4}

The second example should in theory be more loose and return more results, but it doesn't.

I also tried backslash before comma, non-greedy regexp, still nothing.

Any clue ?

The documentation is still a bit confusing on the google page (after 2 years).

Your not working sample should be encoded in this way:

ga%3ApagePath%3D~%5E%2Fboutique-p%5Cd%7B1%2C4%7D

I usually use this website to figure out encoded/decoded strings:

Using the http://ga-dev-tools.appspot.com/explorer/

You can see how it is encoded clicking on the first icon top-left (the one with the world)

The comma is a reserved character (it is used to separate filter expressions. If you want to include it in the expression, it must be escaped with a backslash \,
