Summary
When a user enters a string into a textbox to initiate a search, the developer has to parse that string and convert it to a query of some kind. This little snippet uses a very simple regular expression to extract the keywords from the search string as an array of strings. From this array you can then create your search query.
public static string[] GetSearchWords(string text)
{
string pattern = @"\S+";
Regex re = new Regex(pattern);
MatchCollection matches = re.Matches(text);
string[] words = new string[matches.Count];
for (int i=0; i<matches.Count; i++)
{
words[i] = matches[i].Value;
}
return words;
}
Dont' forget the using directive:
using System.Text.RegularExpressions
