Elasticsearch/Lucene highlight - lucene

Question

How to highlight result query with fuzzyLikeThisFieldQuery in elasticsearch? I can pick up on fuzzyQuery but not fuzzyLikeThisFieldQuery. For example, in the code below i used fuzzyQuery:
QueryBuilder allquery = QueryBuilders.fuzzyQuery("name", "fooobar").minSimilarity(0.4f);
SearchRequestBuilder builder = ds.getElasticClient()
.prepareSearch("data")
.setQuery(allquery)
.setFrom(0)
.setSize(10)
.setTypes("entity")
.setSearchType(SearchType.DEFAULT)
.addHighlightedField("name")
.addField("name");
SearchResponse sr = builder.execute().actionGet();
the result is
If you want to have a <em>foobar</em> for oracle
But if i use fuzzyLikeThisFieldQuery, didn't highlight
QueryBuilder allquery = QueryBuilders.fuzzyLikeThisFieldQuery("name").likeText("fooobar").minSimilarity(0.4f);
the result is
If you want to have a foobar for oracle
Anyone know why?

Answer 1

You need to call these two functions to set the highlighter tags..
builder.setHighlighterPreTags("<pre>").setHighlighterPostTags("</pre>");

Answer 2

I need to highlight the keyword and use the method I've written below works fine for me:
searchRequest.setQuery(
QueryBuilders.queryString(q))
.addHighlightedField("title")
.addHighlightedField("text")
.setHighlighterPreTags("<em>")
.setHighlighterPostTags("</em>");
_searchResponse = searchRequest.execute().actionGet();
I use Gson to parse response string as a json object and cast to my entity like below:
root = new JsonParser().parse(_searchResponse.toString());
p.results.add(root.getAsJsonObject().get("hits").getAsJsonObject().get("hits"));
You will get such a response like this:
content: {
results: [
[
{
_index: "news",
_type: "news",
_id: "111",
_score: 0.6056677,
_source: {
id: "1349298458",
title: "Title text",
text: "Detail text"
},
highlight: {
text: [
" some text <em>keyword</em> some text <em>keyword</em>- some text <em>keyword</em> some text."
]
}
},...
Wish you to get how it works and try it yourself.
