Sphinx search sql_attr_multi - where condition

问题

I need to set an index.

sql_attr_multi = uint categories from query; SELECT item_id, category_id FROM connections WHERE value=2

It works fine If I set the value static.

That value is a variable so I want to assign it through a filter but it doesn`t work because I want to filter "sql_attr_multi" not the $sql.

$cl->setFilter("value", array(2));

Thanks

回答1:

setFilter has to do only with searching ( searchd process ). It's a filter applied to an attribute. The categories sql_attr_multi attribute values can't be changed depending on a condition ( unless you reindex or use updateAttributes). If values doesn't vary much , create for each one a mva attribute.
