Keyword Search

A keyword search package for CSV/Excel/Pandas using boolean expressions.

• It works by processing a query string with field indicator for Pandas Dataframe columns.

• Currently, only .str.contains queries are performed.

• Boolean operations (and, or, and not) are mantained during compilation, following Pandas sintax.

• All further work is done by the Pandas DataFrame.query method.

Searched field should not contain spaces or :.

Examples:

((title:leptospira) and (abstract:vaccine))

Installation

$ pip install keyword-search

Using as a Python package

from keyword_search.query import keyword_search

df_results = keyword_search(df, "(title:Leptospirosis)")
print(df_results)

Using as a CLI application

$ keyword-query papers.csv "(title:leptospira) or (abstract:leptospira)" --delimiter ";" --output results.csv
