Why doesn't wordstat output a large number of subqueries?

Question

Yandex.Direct

When I enter query 2, the frequency should appear as a result, incl. on request 1. Why does Wordstat not display it and can these subqueries be somehow collected? Query 1 - rku 97
250 002 vladasvet - What were searched for with the word "rku 97 250 002 vladasvet" - 27 impressions per month Impressions per month rku 97 250 002 98 lamp rku 97 250 002 66 rku 97 250 002 with glass 54 lamp rku 97 250 002 with glass 44 rku 97 250 002 with glass ip54 27 This is a problem that I run into all the time.

Answer 1

Wordstat does not display queries with too low frequency. Especially if they are difficult to group into single queries. Usually omits requests with a frequency of about less than 20.
Try putting your Request 1 in quotation marks. Most likely it will be "empty". Yandex, as it were, hints that it would be better to use another request, more popular.
Yes, and in light of the emergence of the new status "Few Impressions", low-frequency queries are losing their former attractiveness.
