Hi

Im using Umbraco v6.1.6 and searching against members using Examine (InternalMemberSearcher) and i keep running into this YSOD that states -

The given key was not present in the dictionary.

This happens when trying to iterate over a checkbox list datatype property.

 <h3>Specialisms</h3>
                        <ul>
                            @{                            
                                var specs = item.Fields["specialisms"].Split(',');
                                foreach (var specitem in specs)
                                {
                                    <li>@specitem</li>
                                }
                            }
                        </ul>

Firstly is there a way to first check wether the [specialisms] field is present and has a value?

Secondly why is my InternalMemberSearcher not including this property in its index? i have added it to the ExamineIndex.config in IndexUserFields but it seems everytime i add a new member and then do a search it fails as its not indexed specialisms.

Is there a way i can flush the index when a new user is created programatically so its forced to index the new members properties?

Not sure what else i can do, any ideas?
