As y'all have read, I'm trying to replicate a google-like search on our database. I think that I have the CF and DB (Oracle) logic worked out but I'd like someone else to look it over and see if it's right. I want to search the same way that google does since most people are used to that. I want words separated by spaces, quoted text (a phrase) treated as a single word, + meaning that it must have the word and - that it must not contain the word.
Here's the search page which allows for a search of a few different columns: http://hhp.umd.edu/people/people_search.cfm and here's the code that I use (and any improvements are welcome): <!--- before this, I make the three arrays described here: - search_ar: the OR search items - search_must: the AND "must contain" items, designated as + before the word - search_not: the items that "must not contain" in the returned results, designated as minus before the word ---> <CFQUERY NAME="people_search" DATASOURCE="dpch"> SELECT id,fname,lname,type,title,dept,phone,location,email,summary,imagePath,li nk FROM PEOPLE 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> <cfif (arrayLen(search_must) GT 0 OR (arrayLen (search_ar) GT 0 AND arrayLen(search_must) EQ 0)) AND arrayLen (search_not) GT 0>AND</cfif> <cfif arrayLen(search_not) GT 0> ( <cfloop from="1" to="#arrayLen(search_not)#" index="kk"> UPPER(#PreserveSingleQuotes (the_search_column)#) NOT LIKE UPPER('%#search_not[kk]#%') <cfif kk LT arrayLen(search_not)>AND</cfif> </cfloop> ) </cfif> <!--- ---> AND status = 'active' ORDER BY upper(lname) ASC </CFQUERY> thanks! _____________________________ Daniel Kessler Department of Public and Community Health University of Maryland Suite 2387 Valley Drive College Park, MD 20742-2611 Phone: 301-405-2545 http://hhp.umd.edu ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
