For those moments when the API just isn’t enough, Elasticsearch allows you to write your own custom logic in a script.

Scripting is supported in many APIs including search, sorting, aggregations, and document updates.

Scripts can be passed in as part of the request, retrieved from the special .scripts index, or loaded from disk.

The default scripting language is Groovy, a fast and expressive scripting language, similar in syntax to Java Script.

I need a type of field so that I can place field all over the document, and when one of the fields is updated, all other fields will be updated with the same modification.

This is for a template document so that the field can be labeled "company name" for example, and this label can be replaced with the actual company name, and, when this happens, every other identical field on the document will be updated. This is most easily done via the bookmark / cross-reference facility.

If we try to update a nonexistent document, the update will fail.

In cases like these, we can use the steps, the smaller the opportunity for conflicting changes.Any other method of selecting the text, for example, clicking on the text, will annoyingly send you back to the first place where you set the reference. Give same name if you want to overwrite a previous template.After you have successfully selected the text, you can change the font and size. If you do overwrite, the window will show you two copies of the template with the same name until you come back to the window again.In Step 3., you do not have to close the Fields window, you can move it out of the way, and do the "Insert Reference"as described in Step 6 in multiple places.You can also set new references (Step 3) without closing the Fields window.For many uses of partial update, it doesn’t matter that a document has been changed.For instance, if two processes are both incrementing the page-view counter, it doesn’t matter in which order it happens; if a conflict occurs, the only thing we need to do is reattempt the update.If your module is making a data model change related to entities and fields, and the automatic update process doesn't handle them, then you will need to write a hook_update_N() function that will update the sites for existing users of your module who already had it installed before you made the change, so that they can continue to function. Some notes on hook_update_N() functions: , the Taxonomy Reference field was removed, in place of using the more generic Entity Reference field.This change was not a simple schema update, so the automatic system didn't take care of it.Alternatively you can disable dynamic Groovy scripts by adding this setting to the directory on every node.If your architecture and security is one that does not need worry about the vulnerability, for example your Elasticsearch endpoints are only exposed and available to trusted applications, then you can choose to re-enable the dynamic scripting if it is a feature your application needs.
