It can very well be, we don't even index a wildcard
it depends on language analyzer

e.g. sql analyzer inherits tokenizer from plain file analyzer
which says(regexp):
Identifier = [a-zA-Z_] [a-zA-Z0-9_]*

hence I doubt '*' is indexed

obviously these analyzers could be improved, so it's just about 
adjusting the appropriate .lex file and improve the lexical analysis
also note that 1 char tokens most usually don't make that much sense and 
just unnecessary increase index, so we do them only for full search, I 
think symbols and refs just ignore 1 char identifiers ...
