search logic for phrase

I am trying to get this phrase to work: “Trabajo de cocinero”
currently I am I get 3 results
but if i use the word “cocinero” I get 15 results

I am currently using “AND” for primary logic keyword and “disabled” for secondary.

I think I have tried all the combinations of primary and secondary logic and I get lots of results for “trabajo” but only 2 for “cocinero”

I am sorry, I have tried to understand the documentation but I can’t seem to get this to work correctly…. what should I do? thanks
