Hi - A simple yes or no question, I think.
I want to retrieve highlighting result from a QueryResponse. I know to use the
following:
Map<String, Map<String, List<String>>> highlighting = resp.getHighlighting();
Most of the examples I've seen use the document uid to extract the results
like so:
String key = resultDec.getFieldValue(UID_FIELD);
Map<String, List<String>> map = highlighting.get(key);
I think this is the right way to go, however I did see one code example that
did things a bit differently: They defined a field to query and then used that
field as the id field, like so:
solrQuery.setParam("fl","query");
... peform query ...
String id = (String) resultDoc.getFieldValue("query");
Map<String,List<String>> highlightSnippets =
queryResponse.getHighlighting().get(id);
Our documents have no unique field right now. I can create one rather easily.
However, because of the above example, I've been asked to confirm that the map
returned by highlighting requires/uses the unique key field defined in the
schema.
So, yes or no: Does the highlighting map require a unique key field? ("yes"
could mean "well there are obscure ways to avoid it, but using the unique key
is easier/better/more common").
Thanks,
-Rich
