Multi-value (ie. there may be more than one such attribute declared), optional. Applies to SQL source types (mysql, pgsql, mssql) only. Introduced in version 1.10-beta. String attributes can store arbitrary strings attached to every document. There's a fixed size limit of 4 MB per value. Also, searchd will currently cache all the values in RAM, which is an additional implicit limit. Starting from 2.0.1-beta string attributes can be used for sorting and grouping(ORDER BY, GROUP BY, WITHIN GROUP ORDER BY). Note that attributes declared using sql_attr_string will <strong>not</strong> be full-text indexed; you can use sql_field_string directive for that.</p> <p>所以把 sql_attr_string 换成 sql_field_string 问题完美解决，搜索‘PEPSI COLA 20OZ’也出了想要的结果。</p> amanda_meng Thu, 13 Aug 2015 14:16:00 +0800 https://ruby-china.org/topics/26908 https://ruby-china.org/topics/26908
