I think this is currently already an open issue ([http://github.com/](http://github.com/) elasticsearch/elasticsearch/issues/#issue/307), but I want to make sure I'm not missing something that is currently available in ElasticSearch. Is it possible to control how a highlight's fragments are created? As I read it, the API only allows one to specify the fragment size (in characters), but there's no ability to specify where in a source field that fragment should start or end (say for example at the start or end of a sentence in a document). Or am I missing something? ---

You are correct. It is not possible now. However, there is new feature in master that allows retrieval of whole field content with highlighted tags.

And how do I do that (retrieve whole field with highlighted tags)? Thanks! On Sep 22, 12:08 pm, Lukáš Vlček [lukas.vl...@gmail.com](mailto:lukas.vl...@gmail.com) wrote: > You are correct.

By setting number\_of\_fragments to 0. You can check javaDoc in the following commit > It is also possible to override highlight settings at each field level differently. HTH.
