More coherent helpers for seach results

[rhiaro]

Processing a listing of paged results should be built in.

• Paging by following 'next' links
• Paging by calculating a sequence from the number of results or the 'last' link
• Paging by incrementing a page number until empty result
• Extracting links and titles from the list of results

Started in helpers/init

@sunu This issue is now 4 years old. Is it still relevant or is it a case of close/won't fix?

I think this is still relevant and a nice to have feature but fairly low priority. As Amy said, there are some relevant helpers in helpers/init but we can use more.
