Filter by Word Count of Attribute

Hello I have an index of customer review records and would like to be able to filter by the number of words contained in each review’s review text attribute.

For example filtering to display only reviews that contain 5 words or more.

Is this possible?

Adding the word count as an attribute on my end before importing into Algolia would be a difficult lift, so if I could somehow do it on Algolia’s end, that would be ideal.
