In batch search, spaces are converted to "%20" and yield no match

[flo-schu]

Minimal reproducible example:

import ctxpy
chem = ctxpy.Chemical()

batch search fails, with search value potassium%20bicarbonate

>>> chem.search(by="batch", query=["potassium bicarbonate"])

[{'dtxsid': None, 'dtxcid': None, 'casrn': None, 'smiles': None, 'preferredName': None, 'searchName': None, 'searchValue': 'potassium%20bicarbonate', 'rank': None, 'hasStructureImage': None, 'isMarkush': None, 'searchMsgs': [...], 'suggestions': [...], 'isDuplicate': False}]

exact search works

>>> chem.search(by="equals", query="potassium bicarbonate")

[{'hasStructureImage': 1, 'smiles': '[K+].OC([O-])=O', 'isMarkush': False, 'dtxsid': 'DTXSID0021177', 'dtxcid': 'DTXCID201177', 'casrn': '298-14-6', 'preferredName': 'Potassium bicarbonate', 'searchName': 'Approved Name', 'searchValue': 'Potassium bicarbonate', 'rank': 9}]

Workaround; unfortunately a lot slower

def improved_batch_search(query):
    results = chem.search(by="batch", query=query)
    updated_results = []
    for r, q in zip(results, query):
        if r["dtxsid"] is not None:
            updated_results.append(r)
        else:
            r_new = chem.search(by="equals", query=q)
            if len(r_new) > 1:
                raise ValueError
            updated_results.append(r_new[0])

    return  updated_results
