Description
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>")
