+ * Uses the str_replace() method on a source string.
+ *
+ * @MigrateProcessPlugin(
+ *   id = "str_replace"
+ * )
+ *
+ * To do a simple hardcoded string replace use the following:
+ *
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     source: text
+ *     search: foo
+ *     replace: bar
+ * @endcode
+ *
+ * This example would replace any instance of 'foo' with 'bar' in the values
+ * migrated in via the source field 'text'
+ *
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     source: text
+ *     replace: bar
+ * @endcode
+ *
+ * The above will replace what ever is in the source field 'search_field' with
+ * the string 'bar'.
+ *
+ * You can provide a source field for replacing as well. Using the
+ * 'replace_source' configuration.
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     source: text
+ *     search: "<author>"
+ * @endcode
+ *
+ * You can use both search_source and replace_source at the same time. However,
+ * the Search and Replace configurations will override what ever is provided in
+ * search_source or replace_source if all configurations are provided.
+ *
+ * Both source fields use the
+ * @link Drupal\migrate\Plugin\migrate\process\get get @endlink process plugin
+ * so the use of destination fields are possible like so:
+ * @code
+ *   version_api_search_source:
+ *     plugin: concat
+ *     source:
+ *       - api
+ *       - constants/dash
+ *   field_project_version:
+ *     plugin: str_replace
+ *     source: version
+ *     replace: ""
+ * @endcode
+ *
+ * Case insensitive searches can be achieved using the following:
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     case_insensitive: true
+ *     source: text
+ *     search: foo
+ *     replace: bar
+ * @endcode
+ *
+ * All the rules for
+ * @link http://php.net/manual/function.str-replace.php str_replace @endlink
+ * apply. This means that you can provide arrays as values.
