问题
When using Google Custom Search the TBM parameter for selecting specific types of search engines (e.g. tbm=pts for patents or tbm=blg for blogs) seems to be supported even though this isn't properly documented in the list of parameters.
However when using such "special" searches one usually extend the query by using the TBS parameter, unfortunately this doesn't work for me. For example:
https://www.google.com/?tbm=pts&gws_rd=ssl#q=touch+screen&tbas=0&tbs=ptss:g,ptso:us&tbm=pts
filters correctly when posted from a browser.
But the equivalent custom search:
https://www.googleapis.com/customsearch/v1?key=*MY_KEY*&cx=*MY_ENGINE*&tbm=pts&q=lice+comb&tbs=ptss:g
Completely ignores the TBS parameter.
Is there a way to specify an equivalent parameter in custom search?
