Searching string with Special charactor not working
---------------------------------------------------
Key: LUCENENET-385
URL: https://issues.apache.org/jira/browse/LUCENENET-385
Project: Lucene.Net
Issue Type: Task
Environment: .NET Framework 2.0+, C#.NET, ASP.NET, Webservices
Reporter: Abhilash C R
I have came acroos an issue with search option in our application which uses
Lucene.Net 2.0 version.
The scenario is if I try search a text "Test&&Test" (it is actually
Test&&Test.doc, which is trying to search), it returns 0 hits. While debugging
I could see that the line which wrote to Parse the query is giving the problem,
Here is the error line code:
Query
q=null;
q =
new global::Lucene.Net.QueryParsers.QueryParser("content", new
StandardAnalyzer()).Parse(query);
The variable query at above point contains as this:
(title:(Test&&Test) shorttitle:(Test&&Test) content:(Test&&Test)
keywords:(Test&&Test) description:(Test&&Test) )
and q will get as this:
title:"test test" shorttitle:"test test" content:"test test" keywords:"test
test" description:"test test"
And hence the hit length will be 0 at
IndexSearcher searcher = new IndexSearcher(indexPath);
Hits hits = searcher.Search(q);
I tried adding"\" before &&, tried escape, tried enclosing the text in a "" but
all result the same outcome.
Could anyone please hlep me with any fix to it?
If require I can post the full code here.
Hope to hear from Lucene.Net.
Many thanks
Abhilash
