Incorrect search results if searching by date range and any other criteria

Hi,

I've created a search page that searches records by various criteria and is mostly working fine. However, one of the search criteria is a date range (I'm using the WA Datepicker control for these fields).

If I search for records between 2 specific dates I get the correct results returned. If I search for records using search criteria and not entering any dates I get correct results. If I search for records using a date range and then any other criteria I get all the records returned, not just the correct ones. I've been trying to solve this for all day and so far cannot get it working. It's like the page is ignoring the unique value I also tell it to check for (ACCOUNT_REF) when I use dates and other criteria.

I've attached the two files involved and wonder if anyone can point me in the right direction as to why I'm getting incorrect results.

the first step to troubleshooting search results is to write the SQL statement being generated to the page. add the following code just after the <body> tag to write the sql statement:

php:

SQL: <?php echo($query_rsGetOrderSummaryForSearch); ?><br />

i can see in the Search Server behavior though that you have mixed some "AND" criteria and some "OR" criteria.

by mixing the type like this you are causing the unexpected results.

Hi Jason,

I need to have both AND and OR type search results included. My client wanted the search to allow users to enter multiple criteria and not be restricted to all AND type search results e.g. if they incorrectly entered one piece of data, but entered another correctly it would still find a match on the correctly entered field value.

I built a safeguard in to retrieve results only for the currently logged in user by specifying an AND search on the ACCOUNT_REF value, which is a field in the database matched to a session variable that gets set once the user has logged in. However, this seems to be being ignored when using Date range and any other criteria.

I did as you suggested and wrote the SQL query to the page and got the following:

SQL: SELECT * FROM stg_ordersummary WHERE (ORDER_DATE >= "2011-07-01 00:00:00") AND (ORDER_DATE <= "2011-07-01 23:59:59") OR ((CUST_ORDER_NUMBER = '13735')) AND ((ACCOUNT_REF = 'BWEUROPE')) ORDER BY ORDER_DATE DESC

However, records were returned that were outside of the specified date range. Is this down to the fact that my SQL is only applying the AND operator to the dates and then saying - ok no match there, but there's this OR value on the CUST_ORDER_NUMBER field and I've found records that match that field - so that's what's displaying??

Still puzzled as to why I'm getting records returned for other users though who I'm not logged in as????

yes, exactly, when you mix criteria "AND" and "OR", any matches are included in the result set.

the ACCOUNT_REF value is being ignored because there are other records between the dates specified.

Thank you for your help Jason.
I've changed all of the search criteria to use the AND operator and it's now working. I also applied a filter to the recordset before any search queries were performed so that only records for the currently logged in account were used in the records being searched. This has fixed the issue of records for other accounts being returned now.
