Incosistency when searching for publications

[NisoD]

Describe the Bug

I encountered an inconsistency when searching for publications by title. The search behavior is unpredictable: sometimes it returns results, and other times it doesn't, depending on how the session is restarted.

To Reproduce

Steps to reproduce the behavior:

1. Attempt to search for a specific publication by title using iPython.
2. Observe that in some cases, results are returned, while in others (after restarting the session), no results are found.

Expected Behavior

The expected behavior is to receive consistent search results every time the query is run, regardless of whether the session is restarted.

Desktop:

• Proxy Service: FreeProxies
• Python Version: 3.11
• Operating System: macOS
• Library Version: 1.5

Possible Fix

The issue might be in the _load_url function located in publication_parser.py. I suggest changing the following line:

self._rows = self._soup.find_all('div', class_='gs_r gs_or gs_scl') + self._soup.find_all('div', class_='gsc_mpat_ttl')

to:

self._rows = self._soup.select("div.gs_r.gs_or.gs_scl") + self._soup.select("div.gsc_mpat_ttl")

This should potentially improve the consistency of search results.
