Introducing an example from real life:
You enter a shopping centre and inquire at the information desk where you can buy a "suit". The nice lady behind the counter tells you that you can find a "suit" in the men's department. The lady understands that you are not asking for a "sleeping suit" (nightwear) or a "diving suit" (sports department). If you had asked the lady about “suits”, she would have understood you the same way.
You will have already guessed that the nice lady in the shopping centre corresponds to the Findologic search in the online shop.
Search concepts allow you to select filter values (men's department) for defined search terms. In this way, you can prevent search results such as diving suits and pyjamas from being delivered for semantically ambiguous search queries such as "suit".
