Retrieving DOI for a combination of author, title and date/year

[bnoushin7]

Hi there!

I want to retrieve the DOI for a combination of a title, the first author, and the year. I wanted to use the query method, but there is no date or year filed in it. It also does not allow me to use a title. Here is the example article I want to get its DOI:
title: "The generic name Mediocris (Cetacea: Delphinoidea: Kentriodontidae),
belongs to a foraminiferan"
author : Mark D Uhen
Year: 2006

I tried this but it failed (although I could not find any filed name for the year):

last_name='Uhen'
title = 'The generic nameMediocris (Cetacea: Delphinoidea: Kentriodontidae), belongs to a foraminiferan'

q = works.query(author=last_name, title = title)

Here is the error I got:
UrlSyntaxError: Field query title specified but there is no such field query for this route. Valid field queries for this route are: affiliation, author, bibliographic, chair, container_title, contributor, editor, event_acronym, event_location, event_name, event_sponsor, event_theme, funder_name, publisher_location, publisher_name, translator

Is there any other way or method we can use?
I appreciate any help!
Thanks

What software are you using? Should you change the field name title to bibliographic?

In the browser, the link https://api.crossref.org/works?query.author=Uhen&query.bibliographic=The%20generic%20name&filter=from-pub-date:2006-01-01,until-pub-date:2006-12-31 works for me.

For the date you can use the method filter combined with query.

The generic name

Thank you. But could you please help me how can I integrate filter in julyer notebook(Python)?

last_name='Uhen'
title = 'The+generic+name'
#filter=from-pub-date:2008-08-13,until-pub-date:2008-08-13
q = works.query(author=last_name,bibliographic=title)
print(q.url)

Could you please provide an example for how to combine filter with query?

I'm assuming you are using the crossrefapi library (https://github.com/fabiobatalha/crossrefapi).

from crossref.restful import Works
works = Works()
last_name='Uhen'
title = 'The+generic+name'
q = works.query(author=last_name,bibliographic=title).filter(from_pub_date="2008-08-13", until_pub_date="2008-08-13")

Thank you so much. I really appreciate it.
