摘要：A system () for searching and retrieving documents includes a database (), amemory device (), a user interface device () and a controller (). The database () stores
documents. The memory device () stores software, tokens and an index. The softwareperforms methods according to a background routine () and a foreground routine (). Eachtoken (e.g., speed) has related expressions (e.g., miles per hour, mph, kilometers perhour, and kph) assigned thereto that define the token. The index has documents, havingan occurrence of one of the related expressions for one of the tokens, assigned to theone of the tokens. The user interface device () accepts and sends search queries having atoken and receives information related to the documents, having an occurrence of therelated expressions for the token, responsive to a user interface process (). Thecontroller () is electrically coupled to the memory device (), the user interface device ()and the database (). The controller () manages communications between the memorydevice () and the user interface device () responsive to the foreground routine () in thesoftware to respond to the search queries having the token. The controller () alsomanages communications between the memory device () and the database () responsiveto the background routine () in the software to create the index.
