Question

I need to do a pagination / navigation menu in Sphinx

*(for signs) 0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

And to filter the results.

In the “A” page – just the results starting with “A”

Thanks

But if you do mean sphinxsearch, something like this

sql_query = SELECT id, name, ORD(IF(ORD(name) BETWEEN 48 AND 57 OR ORD(UPPER(name)) BETWEEN 65 AND 90, UPPER(SUBSTRING(name,0,1)), '*')) AS ord, ...
sql_attr_uint = ord 

Would give you a numeric attribute representing the first letter of the name. Can be used with setFilter to only return results matching that value.

Can even be used with setGroupBy to get the number of results matching each ordinal.

Edit to add: Using a Integer Attribute – having got an integer via the mysql ORD function, because attr str2ordinal (nor string attributes for that matter!) allow filtering. Converting yourself to an integer like this allows filtering.

Eg to get only ‘A’ results, could do

$cl->setFilter('ord',array(ord('A'))); 

This works because php’s ord function works the same way as mysql.
