How to search against multiple elements

I'm trying to capture occurrences when multiple criteria are true in an event where elements can exist multiple times in the message.

For example, with the below event I want to capture how often events have an element that is both id=A and width>600.

Because there are multiple walls I can easily filter when any element has an id=A or a width>600, but I cannot figure out how to filter where both criteria are met.

Example message below:

elements: [
   {
      id: A
      width: 585
   }
   {
      id: B
      width: 605
   }
]

You can either leverage the spath command https://docs.splunk.com/Documentation/Splunk/8.0.0/SearchReference/Spath to make the data easier to work with, or look at the answer posted here: https://answers.splunk.com/answers/784418/dynamic-loop-through-a-json-array-looking-for-trig.html#an...

Essentially, you need to create a pairing between id and width, separate them into their own rows, index them out, and then run your search:

{code}
your_base_search
| eval id_zip_width=mvzip(id,width)
| mvexpand id_zip_width
| eval id_zip_width=split(id_zip_width,",")
| eval id=mvindex(id_zip_width,0)
| eval width=mvindex(id_zip_width,1)
| search id="A" and width>600
{code}

Hope this helps!

Like this:

... | eval _raw = mvzip(id, width, "=")
| kv
| where A>600

Be sure to try mine; it should scale better and is much shorter.
