Doğacan Güney updated SOLR-313:
-------------------------------
Attachment: schema.xml
stem-example.xml
solr_document_meta.patch
An kind-of-ugly hackish solution (suggested by Yonik Seeley [who also noted
that it is hackish] on the mailing list) that adds a globally accessible thread
local MetaParams class. This patch also adds a MultiLingualStemFilterFactory
that reads language information from metadata and returns that language's
SnowballFilter.
To pass extra information during indexing, one can add it like this:
<doc>
<field ...
...
<meta name="language" content="German"/>
</doc>
And to pass extra information during search time, one can add it like this:
http://localhost:8993/solr/select?q=........&meta.language=German
Prefix "meta." is used to avoid conflicts with other query parameters.
Also attached is a sample document and schema for testing.

> The idea is to add metadata to documents (besides fields) and enable
> analyzers to access this metadata. A simple use case may be putting language
> information in document metadata and stemming document fields according to
> language.
