https://api.crossref.org/works?filter=type:journalarticle&rows=40&query.title=perovskite%20AND%20light&cursor=*
is not correct result.
I want to search ones with title both containing perovskite and light

Hi. Suggest you try using query.bibliographic:

https://api.crossref.org/works?filter=type:journal-article&query.bibliographic=perovskite%20light

Seems to get you what you are looking for.

But there is still little diffrent. The second result only contains perovskite in its title . Would you please tell me the meaning of querying by bibliographic?

I have the same question about querying by bibliographic. Is it possible to put Author, Title & Publication year after it?

Hello, the query.bibliographic means that the API is only searching in the bibliographic metadata only. The reason the second result comes up is that the journal title has light in it and it would be scored high because both are found.
You can use filters for the publication date in the query as well. The title searched would be the journal title I believe and not the article title and you would be able to query on the author as well.

"The title searched would be the journal title"=> Are you sure? Do you have any document?

What did you mean by the "bibliographic metadata only"? Where can API search more than that?
