Hi troops,
 
As part of a genealogy project, I needed a search that could be more or  less 
specific (and so give more or fewer matches) depending on the User's  
selection of 'Narrow, Wide, Wider'.
 
How have others resolved this?
 
function booleanMatch fineTuneLevel,tStr,tSrcString
  --| Param fineTuneLevel: 1 = exact phrase, 2 = all  words [AND], 3 = any 
string [OR]
if fineTuneLevel =1  then
# Whole match...
if num of  words of tStr=1 then
put (tStr is among the  words of tSrcString  OR\
tStr is among the  tokens of tSrcString) into isMATCH
else put tStr is in  tSrcString into isMATCH
else
# Partial  match...
repeat for each word w in  tStr
if fineTuneLevel =2  then
-- by  Word
put (w is among the words of  tSrcString  OR\
w is  among the tokens of tSrcString) &CR after  isMATCH
else
-- by  String
put (w is in tSrcString)  &CR after isMATCH # Each string
end  if
end repeat
end if
if TRUE is not in  isMATCH then return FALSE
if (fineTuneLevel is in "1,2") AND (FALSE is  in isMATCH) then return FALSE
else return TRUE
end  booleanMatch
