DataViews: Array fields with enableGlobalSearch throw "input.trim is not a function" error

[dsas]

Description

When an array field (like categories: ['Space', 'NASA']) from the test fixtures has enableGlobalSearch: true, the global search functionality throws a TypeError because the normalizeSearchInput function expects a string but receives an array.

Expected behavior: Global search should work with array fields, matching search terms against array values (e.g., searching "NASA" should match items with "NASA" in their categories array).

Current behavior: Throws TypeError: input.trim is not a function when attempting to search with array fields enabled for global search.

Step-by-step reproduction instructions

1. Create a dataview with array field data:

  const data = [
    { title: 'Apollo', categories: ['Space', 'NASA'] },
    { title: 'NASA', categories: ['NASA'] }
  ];

2. Configure fields with enableGlobalSearch: true on the array field:

  const fields = [
    { id: 'title', enableGlobalSearch: true },
    { id: 'categories', type: 'array', enableGlobalSearch: true }
  ];

3. Perform a global search:

  filterSortAndPaginate(data, { search: 'NASA' }, fields);

4. Result: TypeError: input.trim is not a function is thrown
