I am looking for some solution to index external data source (eg: xml) for a umbraco project. Luckily I found examine can do it according to this post http://farmcode.org/post/2010/08/10/Using-Examine-to-index-search-with-ANY-data-source.aspx. However I dont know how examine uses score property to rank the search results. Can external data source use it? Is there any method I need to implement?
Examine for external data source - score property
Examine doesn't use score, Lucene is responsible for scoring.
Unless you're implementing a custom searcher you shouldn't need to worry about scoring.
