I have an Oracle query that I'm trying to get it to work like a
google search. I have a list of words that it can contain
(search_ar) and a list of words that it must contain (search_must)
designated by a +. It will also have a MUST NOT CONTAIN, which will
be designated by a -. So when I do the search "research analysis",
it gives me 49 hits. When I do "research analysis +taag", it gives
me the same 49, even though I know that only 2 of the 49 have the
word taag in it. I figured that it would give me 2 hits and that
this is a bracketing issue for the query and I suppose it might still
be, but I don't see it. How would I write the query to do what I
think is correct. Also, that's how it should work right (if it were
google-like)?
WHERE
<cfloop from="1" to="#arrayLen(search_ar)#" index="ii">
UPPER(#PreserveSingleQuotes(the_search_column)#) LIKE
UPPER('%#search_ar[ii]#%')
<cfif ii LT arrayLen(search_ar)>OR</cfif>
</cfloop>
<cfif arrayLen(search_ar) GT 0 AND arrayLen(search_must) GT
0>AND</cfif>
<cfif arrayLen(search_must) GT 0>
(
<cfloop from="1" to="#arrayLen(search_must)#" index="jj">
UPPER(#PreserveSingleQuotes(the_search_column)#) LIKE
UPPER('%#search_must[jj]#%')
<cfif jj LT arrayLen(search_must)>AND</cfif>
</cfloop>
)
</cfif>
thanks!
