The alternatives are presented as links that trigger the same search, # with the suggested word replacing the typo. # It's win32 speciifc, but should be easy to adapt to *nix. I imagine it would # be easy to reimplement in Perl as well. import os import sys import string import win32pipe def main(): #if main returns 0 the user will get an error message theQuery=os.environ['QUERY_STRING'] #Build an exec string to pass to the OS execString="c:\opt\www\cgi-bin\htsearch.exe " execString=execString + '"' execString=execString + theQuery execString=execString + '" ' #Do the search; put the result page into a temporary file resultsFile=win32pipe.popen(execString, 'r') if (resultsFile): resultsOut=resultsFile.read() resultsTestLine=string.split(resultsOut, "\n") resultsFile.close() if (string.find(resultsTestLine[2], "No match for")!=-1): mispell1=string.replace(resultsTestLine[2], "<html><head><title>No match for '", "") mispell2=string.replace(mispell1, "'", "") ispellString="echo " + mispell2 + " | c:\dos\ispell -a -d //c/dos/english | c:\dos\sed '/^&./!d'" spellFile=win32pipe.popen(ispellString, 'r') if (spellFile): spellOut=spellFile.readlines() spellFile.close() replaceString="Check the spelling of the search word(s) you used.
