Customizing automatic resource generation

You can customize solrconfig.xml and schema.xml generation by providing a yaml-formatted file of options.

You can customize solrconfig.xml and schema.xml generation by providing a yaml-formatted file of options:

auto_soft_commit_max_time

The maximum auto soft commit time in milliseconds.

default_query_field

The schema field to use when no field is specified in queries.

type_mapping_version

The Solr/Cassandra type mapping version.

directory_factory_class

The class name of the directory factory.

enable_string_copy_fields

Specify to enable generation of non-stored string copy fields for non-key text fields. Text data can be tokenized or non tokenized. The enable_string_copy fields is false by default. True creates a non-stored, non-tokenized copy field, so that you can have text both ways.

generate_docvalues_for_fields

Define the fields to automatically configure doc values in the generated schema. Specify '*' to add all possible fields:

generate_docvalues_for_fields: '*' ## You can omit this parameter or not specify a value

or specify a comma-separated list of fields, for example:

generate_docvalues_for_fields: uuidfield, bigintfield

index_merge_factor

The index merge factor.

index_ram_buffer_size

The index ram buffer size in megabytes.

rt

Enable live indexing to increase indexing throughput. Enable live indexing on only one Solr core per cluster.

rt=true

Example to customize the solrconfig and yaml

For example, create a yaml file that lists the following options to customize the solrconfig and yaml:

default_query_field: name
auto_soft_commit_max_time: 1000
generate_docvalues_for_fields: '*'
enable_string_copy_fields: false

Use the dsetool command to create the core and customize the solrconfig and schema generation. Use coreOptions to specify the YAML file, for example:

dsetool create_core nhanes_ks.nhanes generateResources=true coreOptions=config.yaml

Example to create a core with live indexing on

To create the core with live indexing (also known as RT), use the dsetool command to create the core and use coreOptions to specify a YAML file that includes the rt: true setting, for example:

dsetool create_core udt_ks.users generateResources=true reindex=true coreOptions=rt.yaml

where the contents of the rt.yaml are rt: true

You can verify that DSE Search created the solrconfig and schema by reading core resources using dsetool.
