Subject Wildcard Search with Special Characters "#" Not Working
Date Tue, 22 Aug 2017 06:55:51 GMT

I’m using Lucene.Net version in my website to search list of courses.
I have few courses which contains the special character “#” like, C#, C#.Net, etc.

But When I search with the term “C#” it showing 0 results.

I’m using StandardAnalyzer and MultiFieldQueryParser also allowing wildcard search (AllowLeadingWildcard
= true).
Here is my code:
var analyzer = new StandardAnalyzer(Version.LUCENE_30, stopWords);
BooleanQuery query = new BooleanQuery();
var nameParser = new MultiFieldQueryParser(Version.LUCENE_30, new[] { "Column1", " Column2",
" Column3" }, analyzer);
if (!string.IsNullOrEmpty(searchCriteria.CourseName))
query.Add(parseQuery(GetTerms(searchCriteria.CourseName.ReplaceDiacritics()), nameParser),
ScoreDoc[] hits = searcher.Search(query, null, hits_limit, Sort.RELEVANCE).ScoreDocs;
var results = _mapLuceneToDataList(hits, searcher);
return results;

For indexing:
The word “C#” indexed and stored correctly.
doc.Add(new Field("Title", sampleData.CourseName, Field.Store.YES, Field.Index.ANALYZED));

Kindly let me know what I have to do to retrieve the result when I search with the term “C#”.

Thanks & Regards,
