The dictionary consists of phrases (one to five words) that figuratively and accurately describe a customer need. Each vocabulary unit is unique, contains a main noun from natural language, and is accompanied by a figurative illustration and a formula-list of parameter names characterizing specific products assigned by the manufacturer to this unit. A common and identical parameter for all products with these keywords in their name (or, in other words, this consumer category) is the rule for converting demand into units of measurement acceptable for this product category. This rule includes the concept of a unit of measurement, that is, a quantity of a product that allows for easy comparison of prices specified in different units of measurement, including when the product is available in different packaging. In practice, the following applies: the consumer specifies their "essential" need in their native language and enters the keywords either from the keyboard or through a microphone into a speech recognition program. Our dictionary's live search algorithm allows you to immediately find one or a group of dictionary entries with images matching the entered criteria, make your selection, and obtain a formula. After confirming that this is what you need, the buyer can select the parameter values ​​they need from the existing values ​​in the global product catalog. All that's left is to find it within reasonable proximity and at a reasonable price.
