David,
I'm under pressure to permit AND, OR & NOT. My research group insists
that MySQL 4 syntax is "not good enough".
An idea of what one might enter is here (on the bottom):
http://compcanlit.usherbrooke.ca/advanced.html
I was hoping to get away with replacing " AND " with "+", " NOT " with
"-" and " OR " with " ".
I use this as SQL:
SELECT *,MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata->searchenquiry' IN BOOLEAN MODE)
AS relevancy FROM ccl_main
WHERE MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata->searchenquiry' IN BOOLEAN MODE)
ORDER BY relevancy DESC;-->

Any suggestion on how to swap AND OR NOT for mysql fulltext syntax in
$searchenquiry?
A simple parse for " AND " and then str_replace? Is str_replace
appropriate for case?

I think you have a slightly more complex situation than just replacing
text
between what I assume is a LIKE or multiple WHERE situation and a fulltext
search. Perhaps if you can give an idea of the type of string you are
likely to get in $searchenquiry, and to what you wish to convert it, we
might be better placed to give advice.
I can envisage that you might get 'bananas NOT pears AND apples' in the
variable; I guess you would currently manipulate that to a query such as
"WHERE x = 'bananas' AND x <> 'pears' AND x = 'apples'"
(OK that's not a good example) but if you were to feed that to a fulltext
search you might want
WHERE MATCH (x) AGAINST ('+bananas -pears -apples' IN BOOLEAN MODE)
or maybe something else depending on the version of Mysql and exactly what
you are trying to do with your fulltext search.
