How do I determine the index for a specific character string based on its relationship with another character string in the same column?

I have an edf file called 'eventData' with one column of strings (similar to the example shown below). I would like to pull out the indices that idenfity the first instance of the word 'Help' that occurs before the word 'Shoe' appears, and then for all of those identified indices to be saved into a one column double. The problem is that sometimes the word 'Help' occurs in other instances. So in the example below, I would like to pull out the indices for 1 and 11, but not 7. Thank you so much!

What have you tried so far?

You'd need to perform the following procedures:

• DATA import (data read) into MATLAB workspace. Advise to use readtable()
• Employ MATLAB fcn strcmp()
• And use logical indexing and obtain all indexes w.r.t your search

The issue is that I don't know how to do the conditional searching, where I am only interested in obtaining the index of the word help in some cases and not others (details in my question). I already have the data imported.
