4 out of 10 searches go unanswered

By A Bisht

Satya Nadella, head of a research divison at Microsoft, has following to say about search:

** 40 percent of search queries go unanswered or give no results.

** Half of the queries are about searchers returning to previous tasks.

** 46 percent of search sessions are longer than 20 minutes.

Inference: Search as an activity is time consuming. --------
