I decided to try Newsbin Internet Search functionality and got little confused about what "search" means. I found announcement https://forums.newsbin.com/viewtopic.php?f=11&t=30669 where is written that "All Searches are free but queuing search results for download requires a subscription to our Newsbin Internet Search service." . When I read newsbin site about search page then it says "Standard Search with Auto-Renew Six Months 500 per month $15.00 USD ($2.50/month) ".
When I opened new search window in Newsbin, selected Internet in Search mode and performed a search then I got results back. Does the "search" mean downloading something among the results returned from a search like mentioned in the forum announcement post or does the "search" mean performing a search operation in Newsbin search window using Internet as a source?

As far as I understand it, you can use the Search Tab to look for a Binary on the internet - that is free - but to use the link to download the article you need to subscribe to the NBPro Search Service.

This is correct. When you buy a key, it comes with a year of search too.

So it is 1 year and after that I must choose which option I want to purchase.

Yeah. You can then re-up.
