1. A system comprising: one or more processors; a dictionary generator module, implemented using the one or more processors, configured to generate dictionary information that corresponds to a first user, the dictionary information includes a first list of compatible query operators and a description of compatible data types that correspond to each operator in the first list of compatible query operators; a query receiver module, implemented using the one or more processors, configured to receive, from the first user, a search query to search for document information in a database, the database includes an inverted index; a query verification module, implemented using the one or more processors, configured to determine that terms of the search query from the first user are in accordance with the dictionary information that corresponds to the first user; a query processing module, implemented using the one or more processors, configured to apply the search query to the inverted index in the database to identify the document information; and an presentation module, implemented using the one or more processors, configured to send the document information to the first user.
