support for Positional Field Searches

[richardgmcmahon]

I would like to run some positional searches to identify papers with the author is second or third as described here

https://ui.adsabs.harvard.edu/help/search/positional

e.g.

pos(author:”Oort, J”,2) | papers which have “J. Oort” as the second author

I tried q='pos(author:”Oort, J”,2)'

papers = list(ads.SearchQuery(q=q, fl=['id', 'first_author', 'title', 'year', 'citation_count], sort='citation_count desc'))

This returns:
