I have a bit of a strange one, I have an entry in my collection that looks like this...

{
  "alternative_names": "['Walnut Shopping Centre','WSC Trust' ]",
  "id": "39288",
  "name": "The Acorn Market"
}

Searching for

The Acorn Market

returns the result as expected, searching for

Walnut Shopping Centre

also returns the results. But if I search for

WSC Trust

then it does not return. Can anyone spot where I am going wrong?

Difficult to tell what could be going wrong. Can you please share a minimally reproducible dataset and example query?
