I see some things a little differently than Cindy and would like to explain that in more detail in this section. I have carried out some tests based on the research in Cindy's article.
If you search for President with the account settings “Location = Germany & Language=German” the following picture emerges:
Knowledge Panel for the search term “president” in Germany in German
A knowledge panel or entity box for the current German Federal President is displayed.
If you change the settings to “Location = United States & Language=German” it looks like this:
Dictionary for the search term "president" in the USA in German
With the settings “Location = United States & Language = English” it looks like this:
Knowledge Panel for entity type for the search query “president” in the USA in English
For the German search query "präsident", Google kazakhstan phone number data seems to have problems identifying the appropriate entity. Instead, a knowledge panel for the entity type "president" is delivered in the selected language. So Google at least knows that the terms "präsident" and "president" are language-specific names for the same entity type. Interestingly, the SERPs are still delivered in German.
My guess here is that Google does not want to deliver an entity or the current president with the contradictory signals for location, language and German search query. It is not clear whether it makes sense to deliver the German or the American president. Google assumes that you are looking for the president of the United States. However, it is not sure and therefore offers a refinement of the search query below the knowledge panel (Box: See results about).
Another reason would be that, according to the English-language Wikipedia, there is a second entity, namely a car model.
If you change the language of the search query with the same settings, i.e. change “präsident” to “president”, the picture changes:
Knowledge Panel for the search term “president” in the USA in English
Here Google knows exactly that you are looking for the entity Donald Trump as the current President of the USA. If you search for "president" with German language and location Germany, the following happens.
