solr delete query

Solr1.4 Both delete by id and delete by query can be specified at the same time.

Example:

<delete>
  <id>05991</id><id>06000</id>
  <query>office:Bridgewater</query>
  <query>office:Osaka</query>
</delete>

文件编码转换
iconv -f latin1 -t utf8 clear_wk_index.xml > clear_wk_index_.xml

注意solr提交的xml需要是utf8格式，因为里面有中文，默认是latin1格式，会是乱码，所以使用site:xxx删除不了数据

iconv的参数
