Support nested list of objects

In our scenario, we would like to provide full-text search functionality for datasets look like:

{
  "id":"12345",
  "name":"dataset_name",
  "type":"table",
  "columns":[
    {
      "name":"date",
      "type":"int",
      "description":"xxx"
    },
    {
      "name":"container",
      "type":"string",
      "description":"xxx"
    },
    {
      "name":"container_position",
      "type":"int",
      "description":"xxx"
    }
  ]
}

when search container, we hope it could find out all columns having container in its name field. Here is an example:

[
  {
    "id":"12345",
    "...": "...",
    "match":{
      "container":[
        "columns[1].name",
        "columns[2].name"
      ],
      "probably there will be better ways"
    }
  }
]

Looks like currently there is no good way to support this feature. Any thoughts?

A quick and dirty example of what I meant in my previous comment is this function, that given a matched term and the text of the field that matched it, returns the offsets at which the term is found:

const getMatchOffsets = (term, text) => {
  const termRegexp = term.replace(/[.*+?^${}()|[\]\\]/g, '\\$&')
  const matches = [...text.matchAll(new RegExp(termRegexp, 'gi'))]
  return matches.map((match) => [match.index, match.index + term.length])
}

getMatchOffsets('foo', 'the foo in the Foo bar')
// => [ [4, 7], [15, 18] ]

The matched terms and the name of the fields in which they are found are in the match attribute in MiniSearch results. A function like the one above could be used on the results of a search to help highlighting matches, if that is your goal.
