search for subject field results in more hits than shown on website

[Tony Berber-Sardinha]

Dear members

I've run this query to get all the article IDs for 'Veterinary science':

http://api.plos.org/search?q=subject=%22Veterinary%20science/%22&fl=id&start=1&rows=0

this returns 3284 hits:

{
  "response":{"numFound":3284,"start":1,"docs":[]
  }}

But the count of articles for 'Veterinary science' on the website is less: 995.

https://journals.plos.org/plosone/browse/veterinary_science

Is there something wrong with my query?

thank you ahead

tony

Dear Tony,

Thanks for the query! There are two changes that should get you what you want. First, it should be `subject:` not `subject=`, though I’m not sure what difference that will make.

Second, you want to filter by `doc_type:full`, because we index sub-documents.

Third, you want to filter by journal. There are a number of ways to do this, but `journal_id_pmc:plosone` is a good one.

So here is your final query:

curl "http://api.plos.org/search?q=subject:%22Veterinary%20science/%22+and+doc_type:full+and+journal_id_pmc:plosone&fl=id&start=1&rows=0"

which returns 997 entries.

Please let us know any other questions you have!

best, Erik
