I have a requirement to find all the telephone numbers on a medium sized site in all the properties of nodes containing text.

I though I could use Examine for this, but I am having trouble figuring out how to search a bodyText field with a RegEx. I think I am mixing up Examine and Lucene capabilities.

public class PhoneNumberIndexer
{
    public string regex = @"^(?:(?:\(?(?:0(?:0|11)\)?[\s-]?\(?|\+)44\)?[\s-]?(?:\(?0\)?[\s-]?)?)|(?:\(?0))(?:(?:\d{5}\)?[\s-]?\d{4,5})|(?:\d{4}\)?[\s-]?(?:\d{5}|\d{3}[\s-]?\d{3}))|(?:\d{3}\)?[\s-]?\d{3}[\s-]?\d{3,4})|(?:\d{2}\)?[\s-]?\d{4}[\s-]?\d{4}))(?:[\s-]?(?:x|ext\.?|\#)\d{3,4})?$";

    public IOrderedEnumerable<Examine.SearchResult> GetPagesWithPhoneNumbers()
    {
        var searchField = "bodyText";
        var searchTerm = regex;
        var queryTerm = "tel";
        Term t = new Term(searchField, searchTerm);
        RegexQuery regQuery = new RegexQuery(t);

 var searcher = ExamineManager.Instance.SearchProviderCollection["External"];

        if (searcher == null)
            return null;

        var searchCriteria = searcher.CreateSearchCriteria(IndexTypes.Content);
        IBooleanOperation theQuery = searchCriteria.Field("bodyText", regQuery);

I get the error 'The best overloaded method match for 'Examine.SearchCriteria.IQuery.Field(string, Examine.SearchCriteria.IExamineValue)' has some invalid arguments'

Can anyone point me in the right direction please?
