javascript - Vuejs Search filter

I have a table that is presenting a list of items that I got using the following code:

interface getResources {
title: string;
category: string;
uri: string;
icon: string;

}
@Component
 export default class uservalues extends Vue {

resources: getResources[] = [];

created() {
    fetch('api/Resources/GetResources')
        .then(response => response.json() as Promise<getResources[]>)
        .then(data => {
            this.resources = data;

        });
}

}

And this is my table

 <div class="panel panel-default">
                <div class="panel-heading" style="font-weight:bold"><span class="glyphicon glyphicon-align-justify"></span> All Resources</div>
                <div class="row">
                    <div class="search-wrapper panel-heading col-sm-12">
                        <input class="form-control" type="text" v-model="searchQuery" placeholder="Search" />
                    </div>                        
                </div>
                <div class="panel-body" style="max-height: 400px;overflow-y: scroll;">
                    <table v-if="resources.length" class="table">
                        <thead>
                            <tr>
                                <th>Resource</th>
                            </tr>
                        </thead>
                        <tbody>
                            <tr v-for="item in resources">
                                <td><a v-bind:href="item.uri" target="_blank">{{item.title}}</a></td>
                            </tr>
                        </tbody>
                    </table>
                </div>
            </div>

I'm trying to implement a Search bar that filters the results for the user but I'm lost!

Any suggestions?

You can use the includes() function of the array to search any position in a sentence or phrase.

new Vue({
  el: '#app',
  data() {
    return {
        searchQuery: null,
        resources:[
            {title:"ABE Attendance",uri:"aaaa.com",category:"a",icon:null},
            {title:"Accounting Services",uri:"aaaa.com",category:"a",icon:null},
            {title:"Administration",uri:"aaaa.com",category:"a",icon:null},
            {title:"Advanced Student Lookup",uri:"bbbb.com",category:"b",icon:null},
            {title:"Art & Sciences",uri:"bbbb.com",category:"b",icon:null},
            {title:"Auxiliares Services",uri:"bbbb.com",category:"b",icon:null},
            {title:"Basic Skills",uri:"cccc.com",category:"c",icon:null},
            {title:"Board of Trustees",uri:"dddd.com",category:"d",icon:null}
        ]
    };
  },
  computed: {
    resultQuery(){
      if(this.searchQuery){
      return this.resources.filter((item)=>{
        return this.searchQuery.toLowerCase().split(' ').every(v => item.title.toLowerCase().includes(v))
      })
      }else{
        return this.resources;
      }
    }
  }
 

})
