A new filter will appear in the Google Search Console performance report
Google may begin to support the new filter in performance reports in the Search Console. The search engine is working to start filtering using regular expressions. Information about the new filter appeared in the Search Console Help document but was later deleted.
Using the "Special (regular expressions)" filter, webmasters will be able to find elements using regular expressions (wildcard formulas). This filter can be used for page URLs and user requests. For this, the RE2 syntax is used.
When the new filter will be launched is still unknown.
