How to create Custom Search Engine with Yahoo! technologies like Google CSE
Few years ago, I have created custom search engine based on Google CSE. It's good solution to build own "search engine" for specific niche. Unfortunately, this solution is very limited. For example, you can't customize search result as you need. But strong side of Google CSE is ability to search in the list of selected domains only.
How can I build similar CSE using YDN? For example, I want to search documents in selected 2500 websites only.
I see, YahooBOSS can search in selected domains ("sites" param), but length of GET query request is limited. I know, that YQL provides POST requests, but I don't found something similar to "sites" param. May be YDN can provide another solution(s) for my task.
I'll be very happy if YDN community can help me with this question. Btw, I think, if Yahoo can make alternative for Google CSE it will be additional breakthrough.
