Is a known (SEO) issue that if You save a draft post without title, the post_name or slug is immediately saved with the post id.
Later, when You finish your post and put some title, the slug doesn’t change; neither also when your slug preference is %postname%.
So, what if we include the following function to rewrite the slug before publishing the post?

This is a super-simple plugin which will turn WordPress’ default <code>/?s=query%20terms</code> into <code>/search/query+terms/</code> if you have pretty permalinks enabled.
This is something which I have been placing into a theme include or in a core functionality plugin until recently, but it makes sense to separate this functionality out into an individual plugin so it can be switched on and off independently.
The plugin has no administrative interface or control panel. Activation turns it on, deactivation turns it off. Once activated, performing a search using the standard WP search widget should give you a much nicer search URL.

Simple Search Rewrite

Redirects search results from /?s=query to /search/query/, and converts %20 to +.
