Hi Zhe-Xi,
In 2002 Scott A. Crosby implemented full text search for Squeak. Unfortunately it was never integrated and Scott left the community. See the following post: http://lists.squeakfoundation.org/pipermail/squeak-dev/2002-April/037964.htm...
If you search the mailing list for posts from around that time you will probably find more information.
The code seems to be on SqueakMap: http://map.squeak.org/package/6e65267d-53e0-46b0-a4dd-7cb349e18f23 and on SqueakSource: http://www.squeaksource.com/@Xjs1PWixYhd_s5Y1/nsS7RXdi
Most likely some work would be needed in order to make it run.
Cheers, Bernhard

I am planning to implement a search engine just like Google to ease the searching of smalltalk codes in Squeak. The current available search in Squeak has drawbacks in the sense that it goes by the conventional way of information retrieval. I would like to index all the classes, comments and methods in Squeak image to provide an intelligent, faster and efficient way of searching facility in Squeak. This will also help in promoting codes re-usability in the development of Smalltalk.
And then I would like to know if there is a search engine or information retrieval algorithms written in Smalltalk that already made available. If there is such a routine in Smalltalk, could anyone show it to me so that redundant work can be avoided?
