Am having an index of huge content, from which I just want to have the highlighting of the specific text. The highlighted text might have appear as many as times, all I want to have two or more lines before and after the line of highlighted text, by which i can have a snippet of text with highlighted parts are in the middle of the snippet, so that they can be easily located and identified from a huge content of file. Is it possible? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

The only segmentation options are based on characters, sentences, and grabbing the contents of the whole field. The trick with lines is, unless the text contains explicit new lines and you only wrap on new lines, then you have to estimate line breaks based on the rendering context. Stuff like width in pixels and the font. If you want to be precise you need the screen dpi as well and a font rendering engine that works similarly. Some contexts don't properly render ligatures, some do. And its 1000x worse when you leave English and go to something like Arabic or Sanskrit. There be dragons. But, if you are talking about code, or something else with explicit newlines and that only wraps on newlines, then the answer is still no, but it wouldn't be hard to implement.
