Answer 1

Lucene does have its own Sort. Look at the Namespace Lucene.Net.Search.Sort. Below is an example where I am sorting by DateOfMessage.

Lucene.Net.Search.TopDocsCollector collector = Lucene.Net.Search.TopScoreDocCollector.create(InternalMaxSearchResults, false); // default is relevance
var sortBy = new Lucene.Net.Search.Sort(new Lucene.Net.Search.SortField(SearchIndex.IndexFields.DateOfMessage.ToString(), Lucene.Net.Search.SortField.LONG, true));
collector = Lucene.Net.Search.TopFieldCollector.create(
    sortBy,
    InternalMaxSearchResults,   /* max 500 results */
    false,
    false,
    false,
    false);
    break;

// search with the collector
searcher.Search(queryMain, collector);
