Methods and systems for searching a database that includes a plurality of records (204). Each record includes one or more tokens. The one or more tokens include one or more letters, numbers, or symbols. The system includes a user interface that when activated by a user generates at least one of a query symbol or a string of query symbols (208). A processing device compares the generated query symbol or string of query symbols to the stored records (210). An outpu device presents the record or records having tokens that match the generated query symbol or a string of query symbols based on the comparison. (212) The user interface includes two or more input keys (206). Each input key is associated with a query symbol and the number of input keys is less than the number of distinct letters, characters, and symbols. |
