Example

>>> from pprint import pprint
>>> from techminer2.database.field_extractors import ContainsExtractor

>>> # Creates, configures, and runs the extractor
>>> extractor = (
...     ContainsExtractor()
...     #
...     # FIELD:
...     .with_field("author_keywords")
...     #
...     # SEARCH:
...     .having_pattern("FINTECH")
...     .having_case_sensitive(False)
...     .having_regex_flags(0)
...     .having_regex_search(False)
...     #
...     # DATABASE:
...     .where_root_directory_is("example/")
...     .where_database_is("main")
...     .where_record_years_range_is(None, None)
...     .where_record_citations_range_is(None, None)
... )
>>> terms = extractor.run()

>>> # Print the first 10 extracted terms
>>> pprint(terms[:10])
