#3 Various crashing bugs
NLucene is great - when it works.
Unfortunately, it pretty consistently crashes with a
variety of different exceptions when searching text
with a '*' in the search pattern, and various special
characters such as '-' in the text that is indexed. I
hope this can be fixed, because otherwise, NLucene is
really fantastic.
For example, searching for "hcil-*" in my dataset
results in this call stack:
nlucene.dll!DotnetPark.NLucene.QueryParser.TokenList.Peek()
Line 84 + 0xd bytes C#
nlucene.dll!DotnetPark.NLucene.QueryParser.QueryParser.MatchQuery(string

DotnetPark.NLucene.Analysis.Analyzer analyzer =
{DotnetPark.NLucene.Analysis.SimpleAnalyzer}) Line 123
+ 0xd bytes C#
Here is another example with a different crash point
when I searched for 'k*':
