* The unused 'valType' option has been removed from ExternalFileField, if you have this in your schema you
|
||||
can safely remove it. see SOLR-10929 for more details.

* SOLR-10574: basic_configs and data_driven_schema_configs have now been merged into _default. It has data driven nature
|

* Config sets basic_configs and data_driven_schema_configs have now been merged into _default. It has data driven nature
|
||||
enabled by default, and can be turned off (after creating a collection) with:
|
||||
curl http://host:8983/solr/mycollection/config -d '{"set-user-property": {"update.autoCreateFields":"false"}}'
|
||||
Please see SOLR-10574 for details.
|
||||
|
||||
* The data driven config (now _default) for auto-creating fields earlier defaulted to "string" for text input.
|
||||
Now the default is to use "text_general" and to add a copyField to the schema, copying to a "*_str" dynamic field,
|
||||
with a cutoff at 256 characters. This enables full text search as well as faceting. See SOLR-9526 for more.
|
||||
|
||||
* SOLR-10123: The Analytics Component has been upgraded to support distributed collections, expressions over multivalued
|
||||
fields, a new JSON request language, and more. DocValues are now required for any field used in the analytics expression
|
||||
whereas previously docValues was not required. Please see SOLR-10123 for details.

the type mappings, with an optional maxChars limitation. You can also define one typeMappings as default.

expression whereas previously docValues was not required. Please see SOLR-10123 for details. (Houston Putman)

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).

Even if you want to use schemaless mode for most fields, you can still use the <<schema-api.adoc#schema-api,Schema API>> to pre-emptively create some fields, with explicit types, before you index documents that use them.
|
||||
|
||||
Internally, the Schema API and the Schemaless Update Processors both use the same <<schema-factory-definition-in-solrconfig.adoc#schema-factory-definition-in-solrconfig,Managed Schema>> functionality.
|
||||
|
||||
Also, if you do not need the `*_str` version of a text field, you can simply remove the `copyField` definition from the auto-generated schema and it will not be re-added since the original field is now defined.

|
||||
Once a field has been added to the schema, its field type is fixed. As a consequence, adding documents with field value(s) that conflict with the previously guessed field type will fail. For example, after adding the above document, the "```Sold```" field has the fieldType `tlongs`, but the document below has a non-integral decimal value in this field:

If you are working in <<schemaless-mode.adoc#schemaless-mode,Schemaless Mode>>, fields that don't exist will be created on the fly with Solr's best guess for the field type. Documents WILL get rejected if the fields do not exist in the schema before indexing. So, if you are NOT using schemaless mode, pre-create those fields.

== Tips for Custom JSON Indexing
|
||||
|
||||
1. Schemaless mode: This handles field creation automatically. The field guessing may not be exactly as you expect, but it works. The best thing to do is to setup a local server in schemaless mode, index a few sample docs and create those fields in your real setup with proper field types before indexing
|
||||
2. Pre-created Schema : Post your docs to the `/update/`json`/docs` endpoint with `echo=true`. This gives you the list of field names you need to create. Create the fields before you actually index

|

3. No schema, only full-text search : All you need to do is to do full-text search on your JSON. Set the configuration as given in the Setting JSON Defaults section.
