.search(_, search_terms, link_text) ⇒ Object

Search pinboard bookmarks Begin query with ” to force exact matching (including description text) Regular matching searches for each word of query and scores the bookmarks exact matches in title get highest score exact matches in description get second highest score other bookmarks are scored based on the number of words that match

After sorting by score, bookmarks will be sorted by date and the most recent will be returned

Exact matching is case and punctuation insensitive
