search for a string which begins with a '$' character
i am trying to search for a value which begins with a '$' or even sometimes
'$$'. '$' is not listed as a special character and no matter what i try, i
can not get a search for $* to return anything. Using Luke, i browse my
index and see several entries where the value exists with a leading '$'.
How can i search for these?

You're probably getting mislead by storing .vs. indexing.
When you say that the '$' is showing up in Luke, I'm
guessing that what you actually are looking at is the
stored value rather than the indexed tokens. You can
look at both with Luke, but it can be confusing...
FWIW

You can build your custom analyzer using WhitespaceTokenizer + LowercaseFilter. Source code of an existing analyzer will help you.
public TokenStream tokenStream(String fieldName, Reader reader) {
WhitespaceTokenizer tokenStream = new WhitespaceTokenizer(matchVersion, reader);
tokenStream = new LowerCaseFilter(result);
return result;
}

this works, however WhitespaceAnalyzer is case sensitive. Is there a way to
make it case insensitive?

"$" won't survive StandardAnalyzer. You can use WhitespaceAnalyzer instead.

I am using this analyzer: @Analyzer(impl =
org.apache.lucene.analysis.standard.StandardAnalyzer.class)
"$" is not inlcluded in the STOP_WORDS for this analyzer. Is there
somewhere else i should be looking? When i use Luke with the
standardAnalyzer, it does not parse the query. Is there a way to see why?

What analyzer are you using? Did you check that it is making it through your analyzer?
