[SOLVED] Get the matched text in RavenDB v4

Get the matched text in RavenDB v4

In RavenDB < 4, you could get the matched word/sentence from a query/search using the FieldHighlightings class:

FieldHighlightings highlight = null;
hits = session
  .Advanced
  .DocumentQuery<FAOCRPage>("Standard/Lucene")
  .Statistics(out stats)
  **.Highlight(x => x.OCR, 50, 5, out highlight)**
  .SetHighlighterTags("**", "**")
  .Skip(pageNum*pageSize)
  .Take(pageSize)
  .Search(x => x.OCR, queryStr, escapeQueryOptions: EscapeQueryOptions.RawQuery)
  .ToList();

string[] fragments = highlight.GetFragments(hits[0].Id)

And iterate though the highlight variable to get the match text. I RavenDB v4 this class seems to be removed. How can I get the text the was matched in a query/lucene search and not just the document where it was found in?

I.e. if we have the text "This is a small test, they are going nowhere" and searching using wildcard query for "th*", then I would expect the result "this" and "they" and where they occurred in the text.

Is this not possible anymore?

Solution

It's not currently possible in v4.0 but it would be possible with v4.1.

(Planned to be released in a few months).
