Search Reference



Converts a single valued field into a multivalue field by splitting the values on a string delimiter or by using a regular expression. The delimiter can be a multicharacter delimiter.

The makemv command does not apply to internal fields.

See Use default fields in the Knowledge Manager Manual.


makemv [delim=<string> | tokenizer=<string>] [allowempty=<bool>] [setsv=<bool>] <field>

Required arguments

Syntax: <field>
Description: The name of a field to generate the multivalues from.

Optional arguments

Syntax: delim=<string>
Description: A string value used as a delimiter. Splits the values in field on every occurrence of this delimiter.
Default: A single space (" ").
Syntax: tokenizer=<string>
Description: A regular expression with a capturing group that is repeat-matched against the values in the field. For each match, the first capturing group is used as a value in the newly created multivalue field.
Syntax: allowempty=<bool>
Description: Specifies whether to permit empty string values in the multivalue field. When using delim=true, repeats of the delimiter string produce empty string values in the multivalue field. For example if delim="," and field="a,,b", by default does not produce any value for the empty string. When using the tokenizer argument, zero length matches produce empty string values. By default they produce no values.
Default: false
Syntax: setsv=<bool>
Description: If true, the makemv command combines the decided values of the field into a single value, which is set on the same field. (The simultaneous existence of a multivalue and a single value for the same field is a problematic aspect of this flag.)
Default: false


The makemv command is a distributable streaming command. See Command types.

You can use evaluation functions and statistical functions on multivalue fields or to return multivalue fields.


1. Use a comma to separate field values

For sendmail search results, separate the values of "senders" into multiple values. Display the top values.

eventtype="sendmail" | makemv delim="," senders | top senders

2. Use a colon delimiter and allow empty values

Separate the value of "product_info" into multiple values.

... | makemv delim=":" allowempty=true product_info

3. Use a regular expression to separate values

The following search creates a result and adds three values to the my_multival field. The makemv command is used to separate the values in the field by using a regular expression.

| makeresults | eval my_multival="one,two,three" | makemv tokenizer="([^,]+),?" my_multival
