I see how that was a bit cryptic. :-[
'Needle1' was just a word I selected to indicate 'whatever you search for'.
You know the classic:
Needle in a haystack.
Additionally, it is a common practice to use needle as the variable name for the search string in search engines:)
If i want find the thread you made about a glossary I search google for:
needle1 = glossary
user = rodmac
