JustinOrmont added a comment to T136377: Compare ZRR for query features across other search engines.

Quite interesting. To add to TJones' comments, have you looked at what the
ZRR rate would be if you dropped the double quotes from properly quoted ZRR
queries? Aka simulate the automatic removal of double quotes if no (or few)
results were found.

SERPs above look very promising.

JustinOrmont added a comment to T128146: Analyze the varience of user-agent's, country, and other useful metrics of google refered traffic with and without a search query available in referer.

Mobile is likely what you should be optimizing towards. Laptops are going to disappear quickly. Mobile queries can be more difficult due to issues like poor typing, voice recognition queries skew towards full sentences eg, "What is a gubbins?", and a (maybe) more local intent. Local intent ex: "ferry building" when standing in SF should bring up [[San Francisco Ferry Building]].

JustinOrmont added a comment to T127882: Build out a basic tool for running search queries and then recording human judgement of result relevance for use in offline engine scoring.

re: "One possibility is to use nDCG, but this requires having a measure of relevancy from 0..3 for the results."

Restricted Application added a project to T106283: Search on en.wikipedia returns a page twice (one up to date, the other one out of date) : Discovery-Search.

Would it be hard to make a test system to verify the contents of the index?
