Hi Experts,  
I have been trying to highlight some of my matched strings using this:  
HighlightBuilder highlightBuilder = new HighlightBuilder()  
.postTags("")  
.preTags("").field("\_all");  
SearchRequestBuilder searchQuery = client.prepareSearch().setQuery(QueryBuilders.matchQuery("\_all", text)).highlighter(highlightBuilder);

But this is not working. Can someone let me know what I am doing wrong?

Thanks
