Shorten Regex Pattern


Bot needs to find target word in a string, even if the letters of the target word have been seperated by a hyphen, new line break or a digit.

The target word could get different characters between each letter after it’s extracted from a tabular pdf. Here are 2 examples of what the extracted string could be:

  1. “This is a Fai - airies example.”
  2. “This is a Fa- 8 -
    iries example” (new line)

Bot needs to match Fairies for both examples.
The word after and before “Faries” is dynamic. It won’t always be “example” so I cant use example as a keyword. And won’t know beforehand where the new line will be.

This regex pattern works well:


I’m wondering if there is a more efficient/shorter way to write the pattern? Because some target words consist of a 5 word phrase.

Hey @6027ae06be5a67a04d29acc18,

User Fa.+(?=example)|Fa.+\n.+(?=example)



Thanks for the suggestion. I should have clarified that the word after and before “Faries” is dynamic. It won’t always be “example” so I cant use example as a keyword.

String could also be:
“Another Fai-ries story”

Can you check:


Hello @6027ae06be5a67a04d29acc18
Kindly refer this regex pattern



Thank you, this works!

Thanks, this works!

This will generate Peter’s regex pattern for any string as input, in case the word you are searching for is a variable:

"\b" + WordToSearch.First + "(([" + String.Join("", (WordToSearch.Substring(1, WordToSearch.Length-2)).Distinct()) + "]+[\s\S]*?)*?)" + WordToSearch.Last + "\b"

lets preview to another approach as well, simulating more on how a human would handle

The idea:

  • the word of interest is known
  • we start with the first char and ommit anything that is not a letter
  • then the n+1 char is checked if it is same as the n+1 char in the searched word.
  • yes: continue with n+2…
  • no: abort

A strategy like take first char and last char, extracting a part result spanning up this within the text will work for your word but not for a word like “houses” as the ending char also occurs within the token.

I see, thanks
