Regular expressions with google web search

Click For 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 'ChatGPT Examples, Good and Bad'
I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
