Lucene fields default value in Sitecore 7 -

you can create computed field based on original field. if it's empty, homecoming default value:

class="lang-csharp prettyprint-override">public class nulloremptycomputedfield : icomputedindexfield { public object computefieldvalue(iindexable indexable) { item item = indexable sitecoreindexableitem; if (item == null) homecoming null; // homecoming default value if target field empty if (string.isnullorempty(item["originalfield"])) homecoming "_empty_"; homecoming item["originalfield"]; } public string fieldname { get; set; public string returntype { get; set; } }

see next articles tips on creating computed fields:
