defaultSearchTermOptions tweaks

resolves #2737

CHANGELOG-v3.md

@@ -8,6 +8,7 @@
 ### Changed
 - New sites’ Base URLs now default to `@web/`.
 - Textual custom fields now ensure that they don’t contain 4+ byte characters. ([#2725](https://github.com/craftcms/cms/issues/2725))
+- It is no longer expected that all of the `defaultSearchTermOptions` config setting options will be set if any of the default option values need to be overridden. ([#2737](https://github.com/craftcms/cms/issues/2737))
 
 ### Fixed
 - Fixed a bug where the Clear Caches utility was not deleting template caches. ([#2720](https://github.com/craftcms/cms/issues/2720))
