Greetings,
I want to search a portion of a string from a longer string using VLOOKUP. I am using VLOOKUP formula but it fails to provide a needed answer. I attach an example so that you can help me to generate a correct result.
Thank you

You'll struggle with VLookUp.

In the attached are two solutions because in your examples all the smaller strings are to be found at the beginning of the longer strings, but I've included a formula to look the smaller strings anywhere within the longer strings.

In column B is the formula to find the smaller strings anywhere within the longer strings:
In cell B1:
=IFERROR(INDEX(Sheet1!$B$1:$B$4,MATCH("*" & A1 & "*",Sheet1!$A$1:$A$4,0)),"")
copied down.
Note that cell B8 contains a value because it's looking for an empty string and finds it in the row 1.

To find the smaller strings only at the beginning of the longer strings, in C1 array-enter the following (array-entering means committing the formula to thesheet with Ctrl+Xhift+Enter, not just Enter):
=IFERROR(INDEX(Sheet1!$B$1:$B$4,MATCH(A1,LEFT(Shee t1!$A$1:$A$4,LEN(A1)),0)),"")
and copy down.

Thank you very much, the formula is working on some strings bunt not on other strings. I attach examples where the formula is returning a blank cell instead of returning written result

You need to include the extra rows you're returning:
=INDEX(Sheet1!$B$1:$B$4,MATCH("*" & A10 & "*",Sheet1!$A$1:$A$8,0))
needs to be:
=INDEX(Sheet1!$B$1:$B$8,MATCH("*" & A10 & "*",Sheet1!$A$1:$A$8,0))

Thank you for your support but the problem still exists. I attach a full string, so that a problem can be handled once for all.
Sorry for returning

In B1:
A 255 character limit on MATCH with wildcards was breached.
If the smaller strings you're looking for ever exceed 255 characters and it fails, comeback for another (longer) solution.

Thank you, you helped me. God bless you
the formula works
