Scripting disabled: All inline scripting has been disabled in Elasticsearch. You must enable inline scripting for at least one language in order to use scripted fields in Kibana.

Mapping Conflict: You already have a field with the name {{ editor.field.name }}. Naming your scripted field with the same name means you won't be able to query both fields at the same time.

Warning

Format Warning

Formatting allows you to control the way that specific values are displayed. It can also cause values to be completely changed and prevent highlighting in Discover from working.

Proceed with caution

Please familiarize yourself with script fields and with scripts in aggregations before using scripted fields.

Scripted fields can be used to display and aggregate calculated values. As such, they can be very slow, and if done incorrectly, can cause Kibana to be unusable. There's no safety net here. If you make a typo, unexpected exceptions will be thrown all over the place!

Scripting Help

By default, Kibana scripted fields use Painless , a simple and secure scripting language designed specifically for use with Elasticsearch. To access values in the document use the following format:

doc['some_field'].value

Painless is powerful but easy to use. It provides access to many native Java APIs . Read up on its syntax and you'll be up to speed in no time!

Kibana currently imposes one special limitation on the scripts you write. Your scripts must consist of a single expression. Multi-statement scripts with an explicit return statement will not work. In other words, the above example is a valid script, but something like the following is not.

Invalid
def myField = doc['some_field'].value;
return myField;

Coming from an older version of Kibana? The Lucene Expressions you know and love are still available. Lucene expressions are a lot like JavaScript, but limited to basic arithmetic, bitwise and comparison operations.

There are a few limitations when using Lucene Expressions:

  • Only numeric, boolean, date, and geo_point fields may be accessed
  • Stored fields are not available
  • If a field is sparse (only some documents contain a value), documents missing the field will have a value of 0

Here are all the operations available to lucene expressions:

  • Arithmetic operators: + - * / %
  • Bitwise operators: | & ^ ~ << >> >>>
  • Boolean operators (including the ternary operator): && || ! ?:
  • Comparison operators: < <= == >= >
  • Common mathematic functions: abs ceil exp floor ln log10 logn max min sqrt pow
  • Trigonometric library functions: acosh acos asinh asin atanh atan atan2 cosh cos sinh sin tanh tan
  • Distance functions: haversin
  • Miscellaneous functions: min, max
