How can vuetify autocomplete or combobox display multiple record fields and search by them?
For example
one entry => id:2 name:lolo surname:lolololo
item-text="[id,name,last_name]" - not an option

<!-- в данном варианте он ищет по одному полю и выводит id не из v-model -->
<v-flex xs12 sm12 md6 lg6>
    <v-combobox
            :items="users"
            v-model="$parent.searchParam.users"
            label="Пользователи"
            item-text="name"
            item-value="id"
            prepend-icon="people"
            multiple
    >
        <template
                slot="item"
                slot-scope="data"
        >
            <template>
                <v-list-tile-content>
                    <v-list-tile-title>{{data.item.id}} {{data.item.name}} {{data.item.last_name}}</v-list-tile-title>
                </v-list-tile-content>
            </template>
        </template>
    </v-combobox>
</v-flex>

<v-flex xs12 sm12 md6 lg6>
    <v-autocomplete
            :items="users"
            v-model="$parent.searchParam.users"
            label="Пользователи"
            item-text="name"
            item-value="id"
            prepend-icon="people"
            multiple
    />
</v-flex>
