ref : "undefined" in result for search function

[ganeshkbhat]

ref : "undefined" in search result for search. Here is my code and example array:

mdArr = [{body:"# Getting started↵↵↵ Texting xxxx text", url:"/assets/mddocs/intro.md"}, {body:"Another body", url:"/assets/mddocs/intro.md"}]

searchString = 'text'

function searchDocs(mdArr, searchString) {
  let result, docIndex = lunr(function () {
    this.field('url');
    this.field('body');
    for (var i = 0; i < mdArr.length; i++) {
      console.log('lunr', mdArr[i]);
      if (!!mdArr[i].body && (mdArr[i].body.indexOf('Error') !== 0 && !mdArr.err)) {
        let a = mdArr[i];
        this.add(a);
      }
    }
  });

  result = docIndex.search(searchString);
  console.log(result);
  return result;
}

Any help is welcome? Missing something here?

I believe the problem is that you have not specified a ref field, in that case Lunr attempts to retrieve an id field from your docs, but in your case there is none so ref is always undefined.

Seems you want to use the url field as a reference for the documents, I suggest simply changing this.field('url') for this.ref('url'), as described in the "Getting started" guide.

Thank you for your time. this.ref('url') worked and I was able to get the positions as well using this.metadataWhitelist = ['position']; . Kudos for the nice simple and flexible library. ;-)
