本文介绍了如何使用XML格式为Solr创建和更新索引，包括add、commit和optimize等命令的详细用法及参数说明，并提供了实际操作的命令示例。

一个完整的solr的增加索引的xml的格式：

<doc boost="2.5">
<field name="Id">05991</field>
<field name="title" boost="2.0">Bridgewater</field>

<field name="content" boost="4.0">solr is very good search engine!</field>
</doc>

</add>

--------------------------------------------

一：

allowDups = "true" | "false" — default is "false"
commitWithin = "(milliseconds)" if the "commitWithin" attribute is present, the document will be added within that time. Solr1.4
(deprecated) overwritePending = "true" | "false" — default is negation of allowDups
(deprecated) overwriteCommitted = "true"|"false" — default is negation of allowDups

The defaults for overwritePending and overwriteCommitted are linked to allowDups such that those defaults make more sense:

If allowDups is false (overwrite any duplicates), it implies that overwritePending and overwriteCommitted are true by default.
If allowDups is true (allow addition of duplicates), it implies that overwritePending and overwriteCommitted are false by default.

二：

maxSegments = N — default is '1' — optimizes down to at most this number of segments Solr1.3
waitFlush = "true" | "false" — default is true — block until index changes are flushed to disk
waitSearcher = "true" | "false" — default is true — block until a new searcher is opened and registered as the main query searcher, making the changes visible.

用这个命令创建索引文件：

java -Durl=http://localhost:8080/solr/update -Ddata=files -jar post.jar *.xml
