Hi, I've tried this : "$len($regexp(%title%,'[^"]',))" IS 4 to filter on " character but this won't work, but it works on other characters like (-,?,=).
What am I doing wrong?

You want to filter all songs with a `"` character anywhere in the tag TITLE?
Maybe this existing topic can help you:

"It is not possible to filter by strings containing double quotations marks. This is a limitation of the feature."

Thanks for the answer, I want to search for TITLE with a certain number of " characters

If t is not possible to filter by strings containing double quotations marks. Then maybe I can replace the " character with something else and then do the filter?

As you see there is a workaround.
`"$ifgreater($strstr(%title%,$char(34)),0,yes,no)" IS yes`
Still, it is not possible to filter for the quotation marks inside a string.
Which means that you can filter only for the presence of quotation marks.
You could replace them with 2 apostrophes "-\>''
