    Cleansing search term for lucene so it doesn't break

    Using Umbraco And Getting Started
    Umbraco 7

    Does anyone know how to cleanse a search term so that special characters like colons (:), etc. do not break a site search?

    I have:

    // Cleanse the search term
public string CleanseSearchTerm(string input)
{
    return Umbraco.StripHtml(input).ToString();
}

    Thanks.

    Hi Bobi.

    So you want the search to only be able to search for letters or digits? There is probably 100 ways of solving this, but one way is with Regex.

     // Cleanse the search term
        public string CleanseSearchTerm(string input)
        {
            System.Text.RegularExpressions.Regex rgx = new System.Text.RegularExpressions.Regex("[^a-zA-Z0-9 -]");
            input = rgx.Replace(input, "");

            return input.ToString();
        }

    This method would transform this string:

    H|jbfsj08 s989w&/#&%#ยค802 95+43223gf:;:`!

    Into:

    Hjbfsj08 s989w802 9543223gf

    Best of luck!
