弹性搜索的自动完成/前导角度引导

问题描述

我正在寻找一个工作的解决方案，以便在弹性搜索服务器上使用angularjs& bootstrap来获取自动完成/打字。

I was looking for a working solution to get autocomplete/typeahead with angularjs&bootstrap on elasticsearch server.

推荐答案

一个工作的解决方案，而不是一个问题，但我想分享它希望它会帮助：

This is a working solution, not a question, but I want to share it hope it will help:

html代码调用自动完成功能：

the html code to call the autocomplete function :

 <input required type="text"
   popover-trigger="focus"
   placeholder="recherche globale"
   class="form-control"
   ng-model="simplequeryInput"
   ng-model-onblur focus-on="focusMe"
   ng-click="searchSimple=true" ng-keyup="$event.keyCode == 13 ? submitSimple() : null"
   typeahead="item for item in autocomplete($viewValue) | limitTo:15 "
   typeahead-on-select="simplequeryInput=$model"
 />

• 包含弹性搜索（v2.4.0）脚本
  可用

  我的弹性搜索服务

  interfaceApp.service('elasticQuery', function ($rootScope,esFactory) {
    return esFactory({ host: $rootScope.elastic_host}); //'localhost:9200'
  });
  




• angularjs代码查询elasticsearch：

• angularjs code querying elasticsearch :

  'use strict';
  var searchModules = angular.module('searchModules', ['ngRoute','ngDialog']);
  searchModules.controller('searchCtrl', function (ngDialog,$scope, $http,$rootScope, elasticQuery) {
    ...
    $scope.autocomplete = function(val) {
      var keywords = [];
      keywords.push(val);
      // THIS RETURN IS VERY IMPORTANT
      return elasticQuery.search({
        index: 'YOUR_INDEX_NAME',
        size: 15,
        body: {
          "fields" : ["T_FAMILY","T_GENUS","T_SCIENTIFICNAME"], // the fields you need
          "query" : {
          "bool" : {
            "must" : [
              {
                "query_string" : {
                  "query" : "T_FAMILY:"+val // i want only source where FAMILY == val
                }
              }
            ]
          }
          }
        }
      }).then(function (response) {
        for (var i in response.hits.hits) {
          var fields = (response.hits.hits[i]).fields;
          var tmpObject = fields["T_FAMILY"] +" " + fields["T_GENUS"] + " ( "+fields["T_SCIENTIFICNAME"] + " )";
          keywords.push(tmpObject);
        }
      return keywords;
      });
    }
  });
