Find all the words contained in a file and make an index

I import from excel a file that contain all word and created the interested text string (d) :

num,txt,raw] = xlsread('words.xlsx','Hoja1');
d=string(txt);
>>d
d =
Media  
Tao

When searching the web, I discovered that in case of being a word, I can do this, and it returns an index value with the location of that string

Index = find(contains(domain(:,1),'Tao'));

The problem is when I wanna use the file string interested as input (d). I make this e.g.

for (i = 1:d)
    Index = find(contains(domain(:,1),d(i)))
 end

But I receive this:

Index =
  0×1 empty double column vector

I would very much appreciate any help you could give me.

You are on the right track, but you aren't calling the word index correctly. Also, I would suggest using strfind instead of the find(contains(domain( combo. I think it will just provide a more clean answer.

I am having some confusion with your variables, so I am outlining what I am using below. Adjust as you need to.

domain is the large string that you are search and finding indices within.

d is the list of words that you want to find. I am going to assume that it is a cell array of n x 1 size.

Index is the results, where the indices for each word are stored in a numeric array within a cell of Index. The cell number corresponds with the respective word in d.

for i = 1:size(d,1)
    Index{i,1} = strfind(domain(:,1),d{i});
end
