Mans', tags: ['fiction', 'war'] }] var options = { keys: [{ name: 'title', weight: 0.3 }, { name: 'author', weight: 0.7 }] }; var fuse = new Fuse(books, options) fuse.search('Man') /** [{ "title": "Right Ho Jeeves", "author": "P.D. Mans", "tags": ["fiction", "war"] }, { "title": "Old Man's War fiction", "author": "John X", "tags": ["war"] }] */ ```` ### 在字符串数组中搜索 数组中的值可以进行搜索 ``` var books = [{ 'title': "Old Man's War", 'author': 'John Scalzi', 'tags': ['fiction'] }, { 'title': 'The Lock Artist', 'author': 'Steve', 'tags': ['thriller'] }] var options = { keys: ['author', 'tags'] }; var fuse = new Fuse(books, options) fuse.search('tion') /**[{ "title": "Old Man's War", "author": "John Scalzi", "tags": ["fiction"] }]*/ ```
