When performing a custom search (e.g. "tweets by $person", "tweets containing $searchterm" etc.), you are displayed 50 (or however many the preference is set to, maximum of 100) tweets matching the criteria. Two push buttons are displayed (previous and next) and a page number appears. However, upon entering a different page than "1", no results are displayed.
Twitter does not work with pages. I don't know if there is a way to make it work with pages, but Twitter results are not returned in "pages"--instead, they make use of since_id and max_id parameters.
It is relatively easy to isolate the "max_id" you should include in your query to get the next set of results, e.g. in void TwitterSearch::searchResultsReturned(KJob* job): 
QString nextMaxId = QUrl(parser.parse(jj->data(), &ok).toMap()["search_metadata"].toMap()["next_results"].toString()).queryItemValue("max_id"); Unfortunately, I have so far been unable to change twitterapisearchtimelinewidget.cpp to make use of this information.

Reproducible: Always

Steps to Reproduce:
1. Open a Twitter search tab in Choqok.
2. Click "next page"

Actual Results:  
All pages except page 1 are empty.

Expected Results:  
More results should be shown on pages 2, 3, etc.
