C++ Function that Converts A Search String into an SQL Query

We have a C++ / MFC Windows application that stores data in a Microsoft Access format data file. we need a C++ function to help with searching for text in the database. The search conventions below are very similar to the Google Adwords search rules so you can consult them if confused. The function should take a LPCTSTR the user has entered and convert it to a valid SQL query. Lets say the field that will be queried is called: Description So the function would return for the search phrase [dell computer] something like: SELECT * FROM Assets WHERE [Description] = 'dell computer' The format of the text search will be: (1) [Search String] - the data base field must contain EXACTLY what was in between the brackets [ ] and nothing else. So the search: [dell computer] will return only the database rows with a field that contains dell computer if the field contains used dell computer that will not be returned. (2) "Search String" - the data base field must contain the phrase "Search String", it can contain words before or after the phrase: Search String but the phrase "Search String" must be in the Description field. So if the phrase is "dell computer" used dell computer will be returned dell damaged computer would not be returned as "dell computer" must be present in the exact form shown in the quotes. (3) +search a '+' character before a word means the word must be present somewhere in the description field so +dell +computer would return rows containing: dell damaged computer old dell computer computer from dell but would not return dell as the words "dell" and "computer" must be in the description field. (4) -search a '-' character before a word means don't return any rows where the description field contains the word So the search string -queen elizabeth would return rows with a description field containing elizabeth warren elizabeth taylor but would not return rows queen elizabeth queen rock band as they contain the negative keyword: queen
