Otter API - Trackbacks resource

[Shezifi]

Hi,

I am trying to work with the trackbacks resource combined with a query string (to filter results) with not much success...

The results that I get back doesnt include any error, but the amount of results is either zero or I get a few results.

When I am using the Topsy GUI to do the same query I get much more results.

For example:

Searching for result in the 'new york times' that mention 'obama' between the dates 21/01/2011 till 22/07/2012 resolves in 2 results..

http://otter.topsy.com/trackbacks.json?url=http://www.nytimes.com&contains=obama&page=1&perpage=100&mintime=1295568000&maxtime=1342915200&sort_method=date&infonly=0&allow_lang=en 

When executing the same search using the Topsy GUI I get numerous results

http://topsy.com/s?site=http%3A%2F%2Fnytimes.com&mintime=1293832800&maxtime=1342954800&q=obama 

What am I missing? Is there is an issue to combine the 'contain' field in this resource?

It should work according to the documentation

Thanks for the help.
