[Solr Wiki] Update of "AnalysisRequestHandler" by GrantIngersoll

[Apache Wiki <wi...@apache.org>]

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The following page has been changed by GrantIngersoll:
http://wiki.apache.org/solr/AnalysisRequestHandler

New page:
<!> ["Solr1.3"]

The AnalysisRequestHandler is a RequestHandler designed to take in documents as input and return the tokens as output.

It is available via [https://issues.apache.org/jira/browse/SOLR-477]

Input is very similar to UpdateXmlMessages in that a post can be one or more <doc>s, as in

{{{
<docs>
  <doc>
    <field name="employeeId">05991</field>
    <field name="office">Bridgewater</field>
    <field name="skills">Perl</field>
    <field name="skills">Java</field>
  </doc>
  [<doc> ... </doc>[<doc> ... </doc>]]
</docs>
}}}

The docs tag can actually be any value, it need not be docs.  In fact, you could send an <add> to the AnalysisRequestHandler and it should work just fine.

The output will look something like:
{{{

which is wrapped in various wrappers of the NamedList.  The key is that the <arr> tag specifies the field that is tokenized.  The top level <lst> tag name attribute contains the value of the field for the unique key of that document, in this case "VDBDB1A16".
