Michael,

I think we need some more information. Could you show the log from your example and describe why it is not working how you think it should. Also, it seems you have provided sample values of REFERRER_QUERY_STRING, but could you also provide the values for the array variables (Q QUERY KEYWORD)?

Hi all,

I have a quick newbie question with my base sas code I have written that doesn't seem to be doing its thing - what am I doing wrong. i basically have a whole lot of query strings from search engines - each one uses different name pairs that contain the search string that the searcher typed in, which I want to catch and write away

e.g strings look like this rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&q=test and rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&query=test33 and rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&keyword=testingme

So here is what i have written just to evaluate if my logic works which it doesn't seem to be... Please help

tempRefQString = lowcase(URLDecode(Referrer_Query_String)); /* Store's the URL's in a var*/

ARRAY KeyWordsPosArray (3) q query keyword; /* Array of the various CGI name value pairs I need to look for in theURL*/ do i = 1 to 3 ; if index(tempRefQString, KeyWordsPosArray(i)) gt 0 then do; KN_ReferrerExternalSearchWord = 'Y';

/* If any of the array values are in the query string then mark as Y KN_ReferrerExternalSearchWord - so that I know they are being picked up I will do further string manipulations*/ end; end;

Thanks in advance Michael
