Hello,
Yes, getHightlighting() returns a Map<String, Map<String, List<String>>>, so I
first get the map = response.getHightlighting();
Then I initialize a TreeMap with the map object just obtained above (new
TreeMap<>(map)). I then get a collection-view of this treeMap object, like: set
= treeMap.entrySet();
To obtain the order that corresponds with the order returned from a
SolrDocumentList I initialized an ArrayList dynamically, as in:
ArrayList<String> highlightResults = new ArrayList<>();
for(Map.Entry<String, Map<String, List<String>>> me : set) {
highlightResults.add(me.getValue().get("content").get(0));
}
And with that I obtained the desired results.
Thanks for your help.
Leonardo.

Subject: Re: SolrJ getHighlighting() does not return results in order
Hello,
I believe getHighlighting() returns Map<String (docid), Map<String
(fieldName), List<String (snippets)>>> .
Generally Maps are not expected to iterate in order unless you know
the underlying implementation of the Map, for example LinkedHashMap
will iterate in the insertion order and HashMap will not.
You should be able to take the doc id from one of the results in the
document list and then do getHighlighting().get(docid) to get the
Map<String (fieldName), List<String (snippets)>> for the given
document.
Hope that helps.
