Hi I want to implement a search on a website which includes imperfect search results. Meaning, if the search term is misspelled or slightly different from a 100% match, the function should still return results which are sorted by similarity in terms of the search keyword.
I already have implemented algorithms like Smith-Waterman and Needleman-Wunsch which also can be used for database searching. So my idea was to run those algorithms against every keyword in the database and sort them by the score of each result.
Is this a good idea? I am using ASP.NET in C#. Are there any tools or tricks which can accomplish this for me without using my own methods? My biggest concern is performance, after all those algorithms create at least one two dimensional matrix, calculate its values and perform a traceback.
