Generate search data for Hexo 3.x and 4.x. This plugin is used for generating a search index file, which contains all the neccessary data of your articles that you can use to write a local search engine for your blog. Supports both XML and JSON format output.

Install

$ npm install hexo-generator-search --save

Options

You can configure this plugin in your root _config.yml.

search:
  path: search.xml
  field: post
  content: true
  template: ./search.xml
  • path - file path. By default is search.xml . If the file extension is .json, the output format will be JSON. Otherwise XML format file will be exported.
  • field - the search scope you want to search, you can chose:
    • post (Default) - will only covers all the posts of your blog.
    • page - will only covers all the pages of your blog.
    • all - will covers all the posts and pages of your blog.
  • content - whether contains the whole content of each article. If false, the generated results only cover title and other meta info without mainbody. By default is true.
  • template (Optional) - path to a custom XML template

Exclude indexing

To exclude a certain post or page from being indexed, you can simply insert indexing: false setting at the top of its front-matter, e.g.:

title: "Code Highlight"
date: "2014-03-15 20:17:16"
tags: highlight
categories: Demo
description: "A collection of Hello World applications from helloworld.org."
toc: true
indexing: false
---

Then the generated result will not contain this post or page.

How to use this plugin in my Hexo blog?

You have two choices:

  • you don't want to write search engine by yourself. There are many themes that take use this plugin for local searching that works out of box.
  • you are familiar with Ajax and jQuery and would like to write your own search engine. You can implement one by yourself according to the example theme I give. Read the source code of this theme. Generally there are 3 steps:
    1. write a search view. This is the place for displaying a search form and search results ;
    2. write a search script. This script tells the browser how to grab search data and filter out contents what we're searching;
    3. tell hexo to connect the above two part.
