Sphinx 2.0.8 发布了,Sphinx是一个基于SQL的全文检索引擎,可以结合MySQL,PostgreSQL做全文搜索,它可以提供比数据库本身更专业的搜索功能,使得应用程序更容易实现专业化的全文检索。Sphinx特别为一些脚本语言设计搜索API接口,如PHP,Python,Perl,Ruby等,同时为MySQL也设计了一个存储引擎插件。

Sphinx 单一索引最大可包含1亿条记录,在1千万条记录情况下的查询速度为0.x秒(毫秒级)。Sphinx创建索引的速度为:创建100万条记录的索引只需 3~4分钟,创建1000万条记录的索引可以在50分钟内完成,而只包含最新10万条记录的增量索引,重建一次只需几十秒。

修复的 bug 如下:

Issue 1514: A RT index created with ATTACH  was loosing attribute updates after a clean daemon restart.

Issue 1511: An indexing crash when trying to index multi-value attributes from a  PostgreSQL data source .

Issue 1405: A parsing error on interpreting  mixed operand types in a BETWEEN filtering. More precisely, if the left operand in BETWEEN was an integer, the parser was expecting the right operand to be an integer as well, even if the attribute filtered was a float.

Issue 1481: shebang configs, which load external files, are now reloaded by a rotation even if the timestamp of the config is not changed.

Ubuntu 安装方法:

sudo add-apt-repository ppa:builds/sphinxsearch-stable

文:
 

We’re happy to announce that Sphinx 2.0.8, the generally recommended release, is now available.


In case you are wondering, to us, “generally recommended release” means that all features are stable and complete. We know that some of you are already making use of the shiny new features included in the beta release, but we would like to tell the rest of you about Sphinx 2.0.8. This release includes all the latest bug fixes, real-time index support, string attributes, optimized index format, and many other features you’ve come to love.

Here’s a quick overview of some of the more important bugs you will find fixed in 2.0.8:

Issue 1514: A RT index created with ATTACH  was loosing attribute updates after a clean daemon restart.

Issue 1511: An indexing crash when trying to index multi-value attributes from a  PostgreSQL data source .

Issue 1405: A parsing error on interpreting  mixed operand types in a BETWEEN filtering. More precisely, if the left operand in BETWEEN was an integer, the parser was expecting the right operand to be an integer as well, even if the attribute filtered was a float.

Issue 1481: shebang configs, which load external files, are now reloaded by a rotation even if the timestamp of the config is not changed.

Ubuntu users: install our official Launchpad’s repository to get the latest release every week (temporarily only 12.04 LTS packages are available) :

sudo add-apt-repository ppa:builds/sphinxsearch-stable
