转发: search issue with lucene.net 2.9.4.1 CJKAnalyzer special characters like '.','-'

[Zhiqiang Wang <zh...@innocellence.com>]

Greeting

I use lucene.net to fulfill full-text search function, it works well  but find it can’t find out any results if search string containing any special character like '.'or '-'.
For example: Keyword：“ALM-P177”　 It seems working fine, However, when I tried with the keyword
"ALM-P", "ALM-P1", "ALM-P17", there were no results.

I check CJKTokenizer source code and find it can support below three special characters, but when I add other special characters like ‘.’ Or ‘-’, that can’t work.

if (Char.IsLetterOrDigit(c)
|| ((c == '_') || (c == '+') || (c == '#')))
{
        if (length == 0) {
…}


What should I do to solve this issue, would you please give me some suggestions,

Much appreciated
