Hits Object Deprecated in Lucene.Net 3.03, how do i replace it?

c#, full-text-search, lucene.net

Solution

I use Lucene.net 3.0.3, and Search() returns a TopDocs object, which contains a few properties and an array of ScoreDoc elements. Here is an exemple :

Lucene.Net.Search.TopDocs results = searcher.Search(booleanQuery, null, hits_limit);


foreach(ScoreDoc scoreDoc in results.ScoreDocs){
    // retrieve the document from the 'ScoreDoc' object
    Lucene.Net.Documents.Document doc = searcher.Doc(scoreDoc.Doc);
    string myFieldValue = doc.get("myField");
}

Problem

I am working my way through lucene and been stumped on this issue with the Hits object. I have a Using Lucene.Net.Search but for some reason the VS12 Express cannot find the Hits object so the following fails to compile. The compiler complains about this line ``` Hits hits = searcher.Search(booleanQuery, hits_limit); ``` with the following error message Error 1 The type or namespace name 'Hits' could not be found (are you missing a using directive or an assembly reference?) I do not get it, according to the online tutorials alk you need is Lucnen.Net.Search Any Advice ``` // validation if (subqueries.Count == 0) return new List<MATS_Doc>(); // set up lucene searcher Searcher searcher = new IndexSearcher(_directory, false); var hits_limit = 1000; var analyzer = new StandardAnalyzer(Version.LUCENE_30); BooleanQuery booleanQuery = new BooleanQuery(); foreach (Query fieldQuery in subqueries) { booleanQuery.Add(fieldQuery, Occur.SHOULD); } //var parser = new QueryParser(Version.LUCENE_30, searchField, analyzer); //var query = _parseQuery(searchQuery, parser); Hits hits = searcher.Search(booleanQuery, hits_limit); IEnumerable<MATS_Doc> results = _mapLuceneSearchResultsToDataList(hits, searcher); analyzer.Close(); searcher.Dispose(); return results; ```
