Apache Solr Reference Guide Covering Apache Solr 6.0

langid.fallbackFields string none no If no language is detected that meets the
langid.threshold score, or if the
detected language is not on the langid
.whitelist, this field specifies
language codes to be used as fallback
values. If no appropriate fallback
languages are found, Solr will use the
language code specified in langid.fal
lback.
langid.fallback string none no Specifies a language code to use if no
language is detected or specified in lan
gid.fallbackFields.
langid.map.lcmap string determined by
langid.lcmap
no
A space-separated list specifying colon
delimited language code mappings to
use when mapping field names. For
example, you might use this to make
Chinese, Japanese, and Korean
language fields use a common *_cjk su
ffix, and map both American and British
English fields to a single *_en by using
langid.map.lcmap=ja:cjk zh:cjk
ko:cjk en_GB:en en_US:en.

replace
none no By default, fields are mapped as
_. To change this
pattern, you can specify a Java regular
expression in this parameter.
none no By default, fields are mapped as
_. To change this
pattern, you can specify a Java replace
in this parameter.
langid.enforceSchema Boolean true no If false, the langid processor does not
validate field names against your
schema. This may be useful if you plan
to rename or delete fields later in the
UpdateChain.
Content Streams
When Solr RequestHandlers are accessed using path based URLs, the SolrQueryRequest object containing
the parameters of the request may also contain a list of ContentStreams containing bulk data for the request.
(The name SolrQueryRequest is a bit misleading: it is involved in all requests, regardless of whether it is a query
request or an update request.)
Stream Sources
Currently RequestHandlers can get content streams in a variety of ways:
For multipart file uploads, each file is passed as a stream.
For POST requests where the content-type is not application/x-www-form-urlencoded, the raw
POST body is passed as a stream. The full POST body is parsed as parameters and included in the Solr
