=== Store and retrieve scripts
You can store and retrieve scripts from the cluster state using the
<<stored-script-apis,stored script APIs>>. Stored scripts reduce compilation
time and make searches faster.
<<stored-script-apis,stored script APIs>>. Stored scripts allow you to reference
shared scripts for operations like scoring, aggregating, filtering, and
reindexing. Instead of embedding scripts inline in each query, you can reference
these shared operations.
Stored scripts can also reduce request payload size. Depending on script size
and request frequency, this can help lower latency and data transfer costs.
NOTE: Unlike regular scripts, stored scripts require that you specify a script
language using the `lang` parameter.
