Hi,
I would like to know if there is a search engine or information retrieval
algorithms written in Smalltalk available. If there is such a routine in
Smalltalk, could you show it to me?
Thanks.

Smalltalk indexes start at 1.
| haystack |
haystack :=
'Zig,Zag,Wally,Ronald,Bush,Krusty,Charlie,Bush,Bozo' subStrings: $,.
{ 'Washington' . 'Bush' } do: [:i|
|t l|
t := (haystack indexOf: i).
(t = 0) ifTrue: [ ('%1 is not in the haystack' % { i }) displayNl ]
ifFalse: [ ('%1 is at index %2' % { i . t }) displayNl.
l := ( (haystack size) - (haystack reverse
indexOf: i) + 1 ).
( t = l ) ifFalse: [
('last occurence of %1 is at index %2' %
{ i . l }) displayNl ]
]
].
