当我对Solr进行查询时,我得到了这些facet_counts:
'facet_counts' => {
'facet_dates' => {
'photo_added' => {
'2009-12-28T18:00:00Z' => 396386,
'2010-05-28T18:00:00Z' => 415370,
'gap' => '+1MONTH',
'end' => '2011-02-28T18:00:00Z',
},
},
},
但是,当我向查询中添加这些参数中的任何一个时q=*:*:
fq=photo_added:2009-12-28T18:00:00Z
fq=photo_added:2009-12-28T18%3A00%3A00Z
我收到这个作为回应:
HTTP ERROR 400: Invalid Date String:'2009-12-28T18'
当我向查询中添加这些参数中的任何一个时:q=*:*
fq=photo_added:"2009-12-28T18:00:00Z"
fq=photo_added:"2009-12-28T18%3A00%3A00Z"
fq%3Dphoto_added%3A%222009-12-28T18%3A00%3A00Z%22
fq=photo_added%3A"2009-12-28T18%3A00%3A00Z"
我在回复中收到了这个:
<result name="response" numFound="0" start="0"/>
但是当我fq=对我的查询没有约束时,我得到了numFound="8001000",所以这个fq=约束肯定有问题.
如何进行有效的日期构面查询？
什么是我可以在Vim中使用的正则表达式来查找CVS和可能的其他版本控制系统中的冲突？
我特意要求MySQL,但答案可能适用于很多SQL数据库.
如果我有这样的select语句:
select * from users where age > 5;
如何将其分配给新表？
我正在尝试使用Solr与slfj4和logback,当我用CTRL + C关闭Solr时,我收到此错误:
java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
这在编译期间不会发生.
我在版本1.6.4中检查了org.slf4j.spi.LocationAwareLogger.log的方法签名,它似乎是正确的:
public void log(Marker marker, String fqcn, int level, String message, Object[] argArray, Throwable t);

java start.jar etc/jetty.xml
但是当我这样做时:
java start.jar --list-options
我得到几个缺少的模块,我必须手动添加为我的Maven文件的依赖项.我试着加入他们,我会被卡住在寻找一个合适的版本servlet-api将提供javax.servlet.http.HttpServletResponse,即使下载了罐子jetty-servlet有javax/servlet/http/HttpServletResponse.class它里面.这是错误:

assertTrue(message.isPresent());
assertEquals(id, message.get().getId());
