Proto-Turkic: *sogra- ?
Meaning: 1 to search (through) 2 to ask
Russian meaning: 1 обыскивать 2 спрашивать
Karakhanid: soɣrut- 1 (MK)
Middle Turkic: sora- 1, soraɣaq 'search, perquisition' (Pav. C.)
Chuvash: šɨra- 2
Comments: EDT 816. Федотов 2, 466-467 derives the Chuv. form < *sōr(a)- 'ask' (v. sub *sṓra), but the initial š- remains unclear in both cases. Because of this, and because of the Hapax nature of the OT form the it is actually not quite clear whether the root *sogra- exists at all. An argument in its favour is the semantic match between OT and Chagatai and the resulting semantic distinction (*'search (through)') from *sōr(a)- 'ask'.
