Description

• meili server currently does not only return _highlightResult keys for just those specified via the attributesToHighlight search parameter
• this means data that should not even be attempted to be highlighted is still returned.
  • e.g. an array of images under the images key with objects of type {url:string; size: number; h:number; w: number; alt: string}
  • these non-primitive fields are not returned with a value field which is required for highlighting -- see image

• in lieu of (what I imagine is) a larger change, i suggest there be some defensive checks in the autocomplete highlight parsing for the existence of a valid value key in each of the returned _highlightResults

NB. this is touched on in a related issue: #1337 (comment)

Expected behavior

1. not all attributes returned in highlightResult - only those specified via attributesToHighlight
2. the autocomplete frontend parsing to not typeerror when the value key doesn't exist for an attribute highlight result.

Current behavior
autocomplete typeerrors
