Re: Pattern Tokenizer Factory not working with negation regular expression

[Jack Krupansky]

Hyphen indicates as character range (as in "a-z"), so if you want to include 
a hyphen as a character, escape it with a single backslash.

Subject: Pattern Tokenizer Factory not working with negation regular 
expression

Hi,

I need my tokenizer factory , to split on everything expect numbers ,
letters , '&' , ':' and single quote character.

I use 'PatternTokenizerFactory' as below,

<tokenizer class="solr.PatternTokenizerFactory"
pattern="[^a-zA-Z0-9&amp;-:]" />

but, its spiting tokens by space only . not sure what I am doing wrong in
this.

can anybody help me on this??
Thanks
