Search in select field which is related to another collection

We have a collection that has a field related to another collection. When I try to search in that dropdown, some items donot come. Is there something that can be done to make the search better?

e.g.

{
      name: 'Person',
      type: 'array',
      fields: [
        {
          name: 'id',
          type: 'relationship',
          relationTo: 'city',
          label: 'value',
          hasMany: true
        },
        {
          name: 'value',
          type: 'text',
          admin: {
            readOnly: true,
          }
        },
      ],
      admin: {
        components: {
          RowLabel: ({ data: { value } }: any) => {
            return value;
          },
        },
      },
