i'm trying to develop a search that allow me to accomplish this
String to search
This is a text
the user input
this_is_a_text
this a text
tihs a txt <----notes that the user made a wrong input
but always gave me the best coincidence that would by this is a text
I want to know if the possible to do with the use of contains
and freetext
. I'm also i been thinking to do it matching character by character in a method in c# loading all the records because there only 300 hundred and makeing a percentage of equals. But this are just ideas can someone help me.
UPDATE
I tried with the function soundex but it doesn't help me to much...
If you are wanting to do a one off reconciliation of data you are probably best loading both lists to match into C# and then use an edit distance algorithm such as Levenshtein Distance to iterate through best matches. Can be very time consuming but like I say - if you only have to do once...
You could implement this algorithm as a function in SQLServer (a Googling will find you plenty of people who have already done this for you...). Also, algorithms such as these can give unwanted or unexpected matches where a human matcher would have picked another alternative.
Be careful!
You could use a replace method.
var stringToSearch = userInputText.Replace('_', ' ');
试试Soundex 。
