A lot of weired insite search url appear on Google Search Console

Question

There are a HUGE amount of weired search url appear in my Google Search Console.
I stop the wordpress search function, now every search request will reponse 404.
But those url in Search Console just won't gone!
How could I deal with it?
Is there any tool to clear out all weired urls, and update index according to the Sitemap.xml we send?

Sincerely,
Kyle

Well if they in the 'Not Found' section of the report, then Google has found the 404 status, and NOT indexed them anyway. 
As long as they not indexed, it's totally benign. (just annoying) 
Ie your server as 'protected' these URLs from indexing, by returning a 404 status to clients.

'Allow' is the default, so dont actually need to list the things that are allowed. 
You can have 'Allow', but might be clearer to simply list nothing.

alas yes, blocking in robots.txt is NOT recommended. 
Robots.txt only blocks crawling. It does not prevent indexing. 
So by blocking you are ironically allowing them to be indexed. 
Would highly recommend removing the block in robots.txt, and let the 404's take care of it.

Well if they in the 'Not Found' report - its in the 'not indexed' section. 
So google has ALREADY found the 404, it hasnt indexed the URL (if was indexed it already deindexed) 
So you don't need to do any further checks on the ones already in the 'Not Found' report. 
Similarly any others in the 'not indexed' area of the report, are already not indexed.
