DateparserQueryAnalyzer.analyze() called dateparser.search.search_dates()
without any error handling, so internal bugs in the third-party library
propagated all the way up the search/consolidation pipeline and failed
the calling task.
Observed traceback:
File ".../engine/query_analyzer.py", line 140, in analyze
results = self._search_dates(query, settings=settings)
File ".../dateparser/search/search.py", line 294, in search_dates
"Dates": self.search.search_parse(...)
File ".../dateparser/search/search.py", line 168, in search_parse
translated, original = self.search(shortname, text, settings)
File ".../dateparser/languages/locale.py", line 224, in translate_search
[original_tokens[i], original_tokens[i + 1]],
IndexError: list index out of range
Wrap the call in a try/except so any parser failure is treated as
"no temporal constraint found" — the caller can then fall back to
non-temporal retrieval instead of erroring out the whole task. The
failure is logged at WARNING level so we still notice it.
Add a regression test that monkey-patches _search_dates to raise an
IndexError and asserts the analyzer returns an empty constraint and
emits a warning log.
