问题 I'm currently using the highlighting feature that elasticsearch offers in my query. However, the one thing I'm not quite clear on is about how the results are ordered. I would prefer they come back in the order that they appear in a paragraph instead of importance/score. This is so I can concatenate them with ... 's in the same order as they are in the original document (similar to Google results). However, they are currently returning in some weighted order based on best match? Is there a

问题 preface: I'm new and self taught. This is my first coding project. I know it's terrible. I'm going to rewrite it once it's complete and working.

I have HTML fields, and Elasticsearch stomps all over the HTML syntax when I turn on highlighting. Can I make it HTML-aware / HTML-safe when highlighting in this way? I'd like the highlighting to apply to the text in the HTML document, and not to highlight any HTML markup which has

问题 I have written a javaScript file in jQuery that provides a search function. I am trying to figure out how to highlight the word aswell. Bellow is the code.

问题 How would I make a textbox, containing preexisting text, that when the user clicked within it all the text inside it would become highlighted. For example, the same way YouTube does the textboxes for the embed code on their videos. Thanks 回答1: If I've understood your problem correctly, you could use some javascript (untested code): <script language="JavaScript"> function selectText(textField) { textField.focus(); textField.select(); } </script> <input type="text" name="sometext" size="100"

问题 I am trying to use the jquery ui "highlight" effect on an input html element with a background image set in the CSS (A search bar with a magnifying glass). During the "highlight" animation, however, the background image temporarily goes away and then appears once the highlight animation is over. I would like the image to remain throughout the animation.
