Keyword searching feacture for Traditional Chinese value in facet

[artdatabase1234]

Hi there !
I’m wondering that whether Algolia supports Chinese or English keyword searching / full-text searching feature within the value of the facet via api.

For example, here are the two data that I create on my index in json format.

{
  title: 'this is title',
  author: 'this is author',
  year: 1955
},
{
    title: '標題一 標題二',
    author: '作者一 作者二',
    year: 1978
}

I’ve done the following things to Configuration on my index dashboard

I can get the data properly by the following code

  const searchResult = await algoliaIndex.search(
    '', 
    {
      filters: 'author:"作者一 作者二"'
    }
  );

  const searchResult = await algoliaIndex.search(
    '', 
    {
      filters: 'author:"this is author"'
    }
  );

But yet, I can't get the data by the following code

  const searchResult = await algoliaIndex.search(
    '', 
    {
      filters: 'author:"is author"' // still can't get anything even turning "in author" to "author"
    }
  );

  const searchResult = await algoliaIndex.search(
    '', 
    {
      filters: 'title:"標題二"'
    }
  );

In the future, I might have hundreds of data with the same format but different value, and I’ll like to filter them out with the complex filters like {filters: ‘title:“標題二” AND year=1965 OR author:“author”’}, can anyone help me with this issue?
Thanks!
