Regular expressions with google web search

AI Thread Summary
Google's web search does not support regular expressions, limiting the ability to search for strings with variable numbers between specific words. For example, searching for "vehicle runs at *** km/h" will not yield results for any number but will return phrases containing three words before "km/h." The search engine's design prioritizes speed, which restricts its functionality. However, users can utilize the ".." operator to create numeric ranges, such as "Engine runs 1800..2500," to find specific data. Despite this, much technical information may not be formatted for effective retrieval by Google. Alternative search phrases like "Effect of speed on engine performance" can yield more relevant results, although they require manual filtering.

Hi all,

Cam google web search accepet regular expressions? Especially, I need to search strings with any number between two words, for example: "vehicle runs at XXX km/h".

Thank you

"vehicle runs at *** km/h" returns entries containing

vehicle runs at less than 60 km/h
Vehicle runs at speed of 70 km/h

and so on

Three * means you are searching for three separate words. Indeed, both "less than 60" and "spee of 70" contain three words.
This is a straightforward case, because "*" followed by a unit (km/h) push the "*" to be a number.

As far as I know - no. Actually google engine is quite limited - it has to, to be so fast.

Thank you. I haven't found that list. But I think it might be solved by forcing a reasonable number range. As example:
"Engine runs *"-> 150'000 results
"Engine runs 1800..2500" -> 10'000 results and "engine runs" is actually followed by numbers.

Thanks
 
The .. operator creates a numeric search range .

eg Cameras £50..£300

Problem is that not much online technical data will be in a suitable format for Google to find .

Using search formats like ' Effect of speed on engine performance ' or ' drag on vehicles at high speed ' will usually generate much more information but you will then have to sift it manually .

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'
Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
