[comp.sys.mac.hypercard] Boolean-search externals

KOFOID@cc.utah.edu (04/27/90)

    In the last year or so, I read a fairly thorough review on XCMDs and XFCNs
which mentioned two commercially available externals which do Boolean searches
on stacks. One was called XSearch, which makes me think it must be a port of
the popular Boolean-search algorithm found on many mainframes. I have
completely forgotten where I saw the article. I've scanned MacWorld back to
Jan. of 1989 with no luck.

    Can anyone help me with i) The article itself; ii) The external commands
referenced by the article; or, iii) Any other Boolean-search externals which
might be available?

    Cheers,

    Eric.
