Russia at some point instituted a law that all contracts have to be published in a centralized database. So, to award contracts to specific companies, an array of techniques was developed to prevent anyone from using that database to bid on those contracts. The names of the goods are misspelled, spelled using a mix of Cyrillic and Latin alphabets, the items are required to be of specific model with tiny modification from common one that only one (pre-arranged) provider happens to have, unusual names are used for goods, etc. etc. It's a whole branch of art now.
