How to find text in OCR output

Hi,

 

I'm making an app that searches an OCR result an confirms if a certain string is found within the text. I can get the OCR to work with Azure cognitive services easily engouht. What i can't work out is how to search the text for a string and output a true or false if the string is found within the text that is recognised. 

 

The string i am looking for is also dynamic and is held within a variable.

 

Can anyne help?

 

Thanks

Hi @asafweis ,

Could you please share a bit more about the result the OCP returns? Is it a Text string value?

Further, do you want to check if a certain string is in a Text value?

 

Based on the needs that you mentioned, I think the in operator could achieve your needs. I have made a test on my side, please take a try with the following formula:

If(
   "Certain String" in "OCR Result",
    true,
    false
)

If you store the certain string you want to search for within a variable, please modify above formula as below:

If(
    CertainStringVariable in "OCR Result",   /* <-- "OCR Result" represents the Text value that (you mentioned) where you searach your certain string  */
    true,
    false
)

In addition, I also agree with @RandyHayes 's thought almost, I think the Find() function could achieve your needs. Please take a try with the following formula:

If(
IsBlank(Find(CertainStringVariable, "OCR Result")),
false,
true
)

More details about Find function, please check the following article:

Hi @asafweis 

 

Have you explored using the Find function?  That is about the only function for searching a string for another string.

 

I hope that helps you.

Thanks for the help. 

I ended up using the find function and just looked for values above 0, but using 'in' looks just as valid.
