From page 157:

"Glue is essentially a super query log that collects a raft of data about a query and the users interaction with the response. Rem. Tr. at 2808:22809:6 (Allan). The data underlying Glue consists of information relating to (1) the query, such as its text, language, user location, and user device type; (2) ranking information, including the 10 blue links and any other triggered search features that appear on the SERP, such as images, maps, Knowledge Panel, People also ask, etc.; (3) SERP interaction information, such as clicks, hovers, and duration on the SERP; and (4) query interpretation and suggestions, including spelling correction and salient query terms. Id. at 2809:82812:20 (Allan) (discussing RDXD-20.026 to .028). An important component of the Glue data is Navboost data. See id. at 2808:16-20 (Allan) (Glue contains . . . Nav[b]oost information.); Liab. Tr. at 6403:3-5 (Nayak) (Glue is just another name for [N]avboost that includes all of the other features on the page.). Navboost is a memorization system that aggregates click-and-query data about the web results delivered to the SERP. Liab. Tr. at 1804:81805:22, 1806:8-15 (Lehman). Like Glue, it can be thought of as just a giant table. Id. at 1805:6-13 (Lehman). Importantly, the remedy does not force Google to disclose any models or signals built from Glue data, only the underlying data itself. Rem. Tr. at 2809:3-4 (Allan)."

When a graphical browser running Javascript distributed by advertising company or business partner is used, Google measures time spent on the results page (SERP), time spent hovering, as well as tracking what links are clicked; it also records device type, location, language

This data collection is common knowledge to many nerds but www users may be unaware of it

If do not use such a browser running Javascript and if only send minimum HTTP headers, none of this data is collected, except location as approximated from IP address. The later can be user-controlled by sending searches to a remote proxy (set up by the user), or perhaps Tor

IMHO, it is relatively easy to avoid "click-and-query" data collection such as duration on SERP, hovering and tracking clicked links, as well as device type and language, but alternative www clients that prevent it, i.e., not the browser distributed by Google, are not made available as a choice. With this settlement, Google can no longer restrict others from offering choice of alternative www clients

NB. "Cookie:" is not one of the minimal HTTP request headers needed to accomplish a Google search. No cookies are needed

Chromium's policies are tightly tied to Ad-measurement within Google (see Privacy-Sandbox). Quite important since pretty-much every non-Google browser on every-platform blocks third-party cookie tracking.
