Better way to Vlookup - excel

I would like to know if there is a better alternative to Vlookup to find matches between two cells (or Python Dfs).
Say I have the below Dfs,
I want my code to check if the values in DF1 was in DF2, If values exactly match OR if the values partially matche return me the value in the DF2.
Just like the matches in 4th column Row 2,3 returned values.
Thanks Amigo!

Well, as you probably suspected already, you have several options. You can easily search for an exact match, like this.
=VLOOKUP(value,data,column,FALSE)
Here is an example.

Or, consider doing a partial match, as such.
=VLOOKUP(value&"*",data,column,FALSE)
Here is an example.

Oh, you can do a fuzzy match as well. Use the AddIn below for this kind of task.

In Python, it would be done like this.
matches = []
for c in checklist:
if c in words:
matches.append(c)
Obviously, the items in the square brackets are the items in the list.
For Python fuzzy matches, follow the steps outlined in the link below.

Matching Pairs Problem in excel using basic functions

May I know how to check whether the Current Pairs match with the Ideal Pairs by using excel functions?
For example: The Current Pair of 1&8 does not match with the Ideal Pair of 1&14 and 1&29
I would also like to count the total number of matching pairs at the end. I have tried out different methods by using countifs() or match(), but in vain.
Appreciate your answer!
You can try below formula to count all matching pairs.
=SUM(--(IFERROR(XMATCH(B2:B7&C2:C7,F2:F7&G2:G7,0),0)>0))

How to use index and match with two columns?

I have the following case
E.g., I want the two cells in yellow to be the same. For this, I need to find the columns Score 1 and Result, and then find the row 03-Jan so that I get the actual score. Do you have any idea how to solve this? I tried with some match and index but I do not get the solution.
Use INDEX with three matches, the first to find the correct row, while the other 2 find the correct column.
=INDEX($E:$N,MATCH($Q9,B:B,0),MATCH(R$8,$E$2:$N$2,0)+MATCH(R$7,$E$3:$I$3,0)-1)
You want to use an Index(Match),Match())
but what you really want to use is a double XLOOKUP.
I also liked this video to help me learn all of the ways to do a 2d lookup.

Finding Exact Matches in Text Strings with Search

I've included example screenshots and the forumlas bellow. I'm basically trying to run a list of Competitors against a list of searches. The competitor list is static and the searches list will grow and change overtime.
I'm finding it challenging to get consistent results with the search formula. It either is too loose (example A) or too strict (example B).
Is there a way to use the formula to exact match whole words in a text string? Or do I need to get sneaky with a VBA (something I'm not too familiar with). Or should I be doing this in another program?
Thanks!
Example A
So here, my formula works and says that someone searched containing avamere. However, It gives me a false positive on "roseville communities" because it has seville in roseville.
Example A Formula:
SUMPRODUCT(--ISNUMBER(SEARCH($C$2:$C$5,B2)))>0
Example B
So I tried to normalize the competitors with spaces:
Now they're all false.
Example B Formula:
SUMPRODUCT(--ISNUMBER(SEARCH(" "&$C$10:$C$13&" ",B10)))>0

python fuzzywuzzy limit, how does it work?

How exactly does the limit work with pythons fuzzywuzzy module, what does it mean?
matches = process.extract(query, choices, limit=2, scorer=fuzz.partial_ratio)
Limit is generally used in fuzzywuzzy when you need "x" best matching solutions.
So, for example you are comparing the same column of a df to match with each other. It will be the case that 1st match will be the name itself. So, you do limit = 2 do get the 2nd best match.
Ex: column values =['Apple','Banana','Orange','Appl','Banan']
If you want to do fuzzy using same column and see how "Apple" is used in different contexts because of spelling mistakes etc. Now the best match of Apple will be Apple itself, so you do limit=2 do get "Appl" in this case
I hope I was clear

Excel, using a second index match if first is empty

I was wondering if theres an easy way to setup a formula that is an index match one a sheet of data, and then if there was no match, look somewhere else.
I have new results which I want to look up from, then if not I have historical results to look up from. I dont want to combine the data as I dont want the historical numbers to change any averages in the new results.
I could use two columns each with a different index match and then some IF, OR statements but I'd like to know if theres a way of doing it all in one forumla.
Thanks
MATCH will return an error where a matching value is not found. This can be used to switch to an alternative match attempt, eg:
=IFERROR(INDEX(Sheet1!A:A,MATCH(C1,Sheet1!B:B,0)),INDEX(Sheet2!A:A,MATCH(C1,Sheet2!B:B,0)))
