Search that supports all valid characters in a Unix filename

[Ed Murray <ma...@avenuedesign.net>]

Could
someone let me know the best Analyzer to use to get an exact match on a Unix
filename when it is inserted into an untokened field. 


Filenames
obviously contain spaces and forward slashes along with other characters. I am using
a WhitespaceAnalyzer but when the query is parsed it is
chopped into different keywords as such: 


I have
tried several different Analyzers but I can’t seem to get what I want.






Filename:
/repository/Administration/780 IT Support/filegate.txt 
Query:URL:/repository/Administration/780
URL:IT URL:Support/filegate.txt






I am
assuming that this would be in common usage with Lucene but there does not seem
to be an easy way to do it.

The usual way to enable this is using PerFieldAnalyzerWrapper, with
KeywordAnalyzer on the Unix filename field.
