php - 如何设置表的优先级？

Question

我有 4 个表来执行索引。我的问题是，

I want to get search results not by weight but by tables priority. I mean table 1 matched results show first then for table 2 and so on.

Currently, it is retrieving results by highest weight first.

查询

Select UUID_SHORT() AS sphinxid, info as keyword, 'column_name' as type from table 1 
UNION ALL 
Select UUID_SHORT() AS sphinxid,  info as keyword, 'column_name' as type from table 2 
UNION ALL 
Select UUID_SHORT() AS sphinxid,  info as keyword, 'column_name' as type from table 3 
UNION ALL 
Select UUID_SHORT() AS sphinxid,  info as keyword, 'column_name' as type from table 4;

如果仍然使用原来的SphinxAPI，有一个SetIndexWeights。 http://sphinxsearch.com/docs/current.html#api-func-setindexweights 尽管必须将数据拆分为单独的实际索引。

...SphinxQL 中没有类似的东西。据我所知

向索引添加新属性可能是最简单的

sql_query =   \
Select ...,8 as multiplier from table1  \
UNION ALL  \
Select ...,4 as multiplier from table2  \
UNION ALL  \
...

sql_attr_uint = multiplier

然后在运行查询时，可以使用该因素

sphinxQL> SELECT id,WEIGHT()*multiplier AS w FROM index WHERE MATCH(..) ORDER BY w DESC;
