In Nuxt Content, you can search your content thanks to the experimental feature called ContentSearch.

first you have to enable this option in your nuxt.config.ts

export default defineNuxtConfig({
  content: {
    experimental: {
      search: true
    }
  }
})

and then use it in your components

<script lang="ts" setup>
const search  = ref('')

const results = searchContent(search)
</script>

<template>
  <main>
    <input v-model="search">

    <pre>{{ results }} </pre>
  </main>
</template>
