Evaluation of filter and select fields and alternative implementation of `oa_query`

[rkrug]

Hi

I have written an alternative implementation of oa_query with the following features:

1. uses local validation of filter names and select fields arguments
2. using httr2 based url creation
3. results and arguments are identical to oa_query()

Please take a look at the implementation in the following files:

• filter name evaluation: https://github.com/rkrug/openalexPro/tree/dev/R#:~:text=opt_filter_names.R
• select fields evaluation: https://github.com/rkrug/openalexPro/blob/dev/R/opt_select_fields.R#:~:text=opt_select_fields.R
• pro_query implementation:https://github.com/rkrug/openalexPro/blob/dev/R/pro_query.R#:~:text=pro_query.R

I would be happy to open a pull request if there is interest

Cheers

Rainer

Thank you for this issue, Rainer! I don't love the change in dependency from httr to httr2, but I'll take a look at your filter implementation.

Hi Trang.

The httr2 move is different to the query builder - the qury builder just needs one API call and this couylod also be done using httr.

Cheers,

Rainer
