An index associated with a database is dynamically processed in an information retrieval system to create a set of questions for use when processing a data inquiry from a user. The index, a structured guide used when searching the database, has different information domains. After one of these domains is selected, a particular order of the index categories within the selected domain is determined, typically by referring to the order lookup table within the index. A script corresponds to the selected domain. Within the script, there are questions corresponding to each index category within the selected domain. These questions are dynamically used to prompt the user. Only the questions corresponding to active index categories are arranged into the set of questions having a question set order corresponding to the particular order of the index categories. In an iterative process, the first question is identified and used to prompt the user to select a term from a scaled down vocabulary of terms (i.e., only those terms associated with the first question and corresponding first index category). Upon selecting the term, a search of the database is performed by the search engine module based upon the selected term. If there is too much information returned from the search, the next question is identified and the iterative process is repeated.
