{
var documentHightlightMap = documents.ToDictionary(c => c._id.ToString());
var reader = DirectoryReader.Open(writer, true, true);
var queryParser = new HighlighterQueryParser(writer.GetAnalyzer());
queryParser.SetMultiTermRewriteMethod(MultiTermQuery.SCORING_BOOLEAN_REWRITE);
var query = queryParser.Parse(criteria.Query)
.Rewrite(reader);
var highlighter = CreateHighlighter();
