SharePoint Dragons

If you want to add a property to the spweb property bag, you might want to consider to ad dit to the IndexedPropertyKeys collection as well. This causes the creation of a new crawled property the First time after a full crawl has taken place. The code looks something like this:

using (var site = new SPSite(“http://thesite_coll_url”))

            {

using (var web = site.OpenWeb())

                {

string propKey = “lctest”;

string propValue = “lcvalue”;

                    web.AllProperties[propKey] = propValue;

if (!web.IndexedPropertyKeys.Contains(propKey))

                    {

                        web.IndexedPropertyKeys.Add(propKey);

                    }

                    web.Update();

                }

            }
