positional ("cone") search - backend

[ehenneken]

• Instead of bibcodes, the service should return SIMBAD identifiers
• The endpoint should be renamed to cone

[ehenneken]

• check whether correct results are returned (specifically use of epoch / coordinate systems)

According to Alberto, the query

http://adsabs.harvard.edu/cgi-bin/abs_connect?data_type=VOTABLE&DEC=60&RA=16&SR=.1

should return 1 (A&A?) document. This is correct: it should return 1995A&AS..114..269D

This works:

• Clone master locally
• Add proper local_config.py
• Run a local cone search (e.g. object:"16 +60:0.1")

This does not work:

• Deploy same master in dev
• Run the same query against dev

The object-service micro service in dev fails with an internal server error and the logs say:

There seems to be a problem with verify_query in utils.py. However, it only occurs when deployed in AWS.
