Make the UpdateRequestProcessorChain the Default for the UpdateRequestHandler
Once the UpdateRequestProcessorChain has been defined, you must instruct your UpdateRequestHandlers to
use it when working with index updates (i.e., adding, removing, replacing documents). Here is an example using
InitParams to set the defaults on all /update request handlers:
add-unknown-fields-to-the-schema
After each of these changes have been made, Solr should be restarted (or, you can reload the cores to
load the new solrconfig.xml definitions).
Examples of Indexed Documents
Once the schemaless mode has been enabled (whether you configured it manually or are using data_driven_
schema_configs ), documents that include fields that are not defined in your schema should be added to the
index, and the new fields added to the schema.
For example, adding a CSV document will cause its fields that are not in the schema to be added, with
fieldTypes based on values:
curl "http://localhost:8983/solr/gettingstarted/update?commit=true" -H
"Content-type:application/csv" -d '
id,Artist,Album,Released,Rating,FromDistributor,Sold
44C,Old Shews,Mead for Walking,1988-08-13,0.01,14,0'
Output indicating success:
0106
The fields now in the schema (output from curl http://localhost:8983/solr/gettingstarted/sche
