spring-data-elasticsearch: Highlighter not working -

-



i'm working spring-data-elasticsearch:2.1.6.release library, , can't seem able highlighting working. right now, query looks so:

    searchrequestbuilder request = client             .preparesearch("stuff")             .setsearchtype(searchtype.query_then_fetch)             .setquery(matchquery)             .setfrom(from)             .addhighlightedfield("description", 10, 5)             .addhighlightedfield(new highlightbuilder.field("title").pretags("<b>").posttags("</b>"))             .addhighlightedfield(new highlightbuilder.field("description").pretags("<b>").posttags("</b>"))             .sethighlighterpretags("<br>")             .sethighlighterposttags("</br>")             .setsize(pagesize);

as can see, i'm trying under sun. no matter do, nothing seems work.

further down in code, decided see fields might highlighted in searchhit with:

final map<string, highlightfield> stringhighlightfieldmap = hit.highlightfields(); highlightfield = hit.gethighlightfields().get("description");

in both cases, values either null or "size=0".

i've seen on stackoverflow response here how provide highlighting spring data elasticsearch , when try that, still there no highlighted fields.

does know how highlighting work spring-data-elasticsearch?

any appreciated.
