如何获取准确的搜索结果在角度4

Question

我已经在我的应用中实现了搜索模块。该搜索不会搜索确切的短语，而是分别搜索该短语中的每个单词。例如，如果您搜索“ Comprehensive Metabolic”，则只希望看到CMP面板，但是搜索实际上返回的每个面板都有单词“ Comprehensive”或“ Metabolic”，这是一个更长的列表。 我可以获得任何帮助吗？

我可以使用任何管道来过滤精确搜索吗？

这是我的搜索组件html

if(myCart != default(ShoppingCart)){
    // do stuff
}

其Ts文件

import json
import pickle
import numpy as np
import boto3

s3 = boto3.resource('s3')

# Function for transferring pickles from s3 to lambda 
def download_files_from_s3():
    with open('/tmp/km_model_on_space_data.pkl', 'wb') as f:
        s3.Bucket("ml-model-first-try").download_fileobj("km_model_on_space_data.pkl", f)
    with open('/tmp/tfidf_vectorizer.pkl', 'wb') as f:
        s3.Bucket("ml-model-first-try").download_fileobj("tfidf_vectorizer.pkl", f)
    with open('/tmp/cluster_distances.pkl', 'wb') as f:
        s3.Bucket("ml-model-first-try").download_fileobj("cluster_distances.pkl", f)
    with open('/tmp/space_ids_only.pkl', 'wb') as f:
        s3.Bucket("ml-model-first-try").download_fileobj("space_ids_only.pkl", f)

# Downloading files from s3 to lambda ------------ Comment the next line if data is already downloaded
download_files_from_s3()

# Loading pickles
km = pickle.load(open('/tmp/km_model_on_space_data.pkl','rb'))
tfidf_vectorizer = pickle.load(open('/tmp/tfidf_vectorizer.pkl','rb'))
cluster_distances = pickle.load(open('/tmp/cluster_distances.pkl','rb'))
space_ids = pickle.load(open('/tmp/space_ids_only.pkl','rb'))

# Automatically called everytime
def lambda_handler(event, context):
    tfidf = tfidf_vectorizer.transform([event['text']])
    cluster = km.predict(tfidf)
    cluster_arr = cluster_distances[:,cluster[0]]
    cluter_arr_sorted = cluster_arr.argsort()
    recommended_space_ids = []
    for i in cluter_arr_sorted[0:10]:
        recommended_space_ids.append(space_ids[i])
    return {'Cluster_Number' : cluster[0], 'Space_Ids' : recommended_space_ids}

我将此添加到了我正在使用的组件中

此处是父组件的html

  <input #searchInput type="text" (focus)="onFocus($event)" (blur)="onBlur($event)" (keyup)="onKeyUp($event)" placeholder="Search">

其Ts文件

  @Input() searchTerm: string = "";
  @Output() onSearchInputUpdate = new EventEmitter();
  @ViewChild("searchInput") searchInputField: ElementRef;

  public searchFocus: boolean;

  private searchTermTimeoutId;
  private waitTime: number = 500; // half a second


    onBlur(event) {
// setTimeout so clearSearch click event has time to be called first
setTimeout(() => {
  if (event.srcElement.value.length === 0) {
    this.searchFocus = false;
  }
}, 100);
 }

  onKeyUp(event) {
 if (this.searchTermTimeoutId) {
  clearTimeout(this.searchTermTimeoutId);
 }
this.searchTermTimeoutId = setTimeout(() => {

this.onSearchInputUpdate.emit(this.searchInputField.nativeElement.value);
  }, this.waitTime);
 }

我得到的所有结果都有综合性或代谢性。 像这样 我该怎么做才能得到确切的结果 有什么帮助吗？ 谢谢
