Regex-Filtering segments with less than a specific number of words

Hello

I would like to filter segments that have for example less than 10 words on Studio file

I think the only way is to find a regex expression that allows me to identify words and limit to a specific number but i could be wrong

I tried to identify words using "[A-Za-z0-9]+" but how can i say to the filter to show ONLY segments with less than 10 words for example?

I was trying the "{min,max}" regex but with no sucess

Does anyone have an idea? or work around?

Many thanks
