=== Search templates
You can also use the `_scripts` API to store **search templates**. Search
templates save specific <<search-search,search requests>> with placeholder
values, called template parameters.
You can use stored search templates to run searches without writing out the
entire query. Just provide the stored template's ID and the template parameters.
This is useful when you want to run a commonly used query quickly and without
mistakes.
Search templates use the http://mustache.github.io/mustache.5.html[mustache
templating language]. See <<search-template>> for more information and examples.
