False positives when searching dates

[g-kozulis]

OS: Windows 10.0.17763.805
dateparser version: 0.7.2

When using the search_dates() function some numerical and punctuation mark combinations that don't resemble any date format I've ever seen get picked up as dates.

To reproduce run the following code and replace <false positive> with any one of the following:

• 8: 100M2_
• 100M
• 10,00 2
• 19,60 5
• 73 20

from dateparser.search import search_dates

search_dates("The following isn't a correct date <false positive>")

Same here on OSX 10.15 with version 0.7.2

Here are some examples of results that should not be dates

search_dates(text,languages=['en'], settings={'STRICT_PARSING': True,'PREFER_DATES_FROM': 'past','DATE_ORDER': 'DMY'}, add_detected_language=True)

-- Clearly wrong
('32° 34’S', datetime.datetime(2013, 10, 16, 23, 59, 7), 'en')
('123°', datetime.datetime(1900, 1, 1, 1, 2, 3), 'en')
('6005', datetime.datetime(2000, 6, 5, 0, 0)
('000', datetime.datetime(1900, 1, 1, 0, 0), 'en')
('of 629', datetime.datetime(1900, 1, 1, 6, 2, 9), 'en')
('>21', datetime.datetime(1900, 1, 1, 2, 1), 'en')

-- I can kind of see where it is getting this but I think it is wrong to do it
('3533', datetime.datetime(2033, 5, 3, 0, 0), 'en')

-- I have lots of numbers in these docs. It should not pick them up and 'make' a date from them
('538400', datetime.datetime(8400, 3, 5, 0, 0), 'en')

FYI some cases will be fixed in the next version (after merging this: #786)

[gavishpoddar]

Seems #786 has been merged, can you please close this issue

[Gallaecio]

Does #786 fix all cases reported here? Otherwise, it makes sense to keep this open.
