hashedixsearch is a lightweight in-process search engine for Python, with support for stemming, custom token analyzers, and query match highlighting.
from hashedixsearch import HashedIXSearch
doc = 'find the needle in the haystack'
index = HashedIXSearch()
index.add(doc_id=1, doc=doc)
results = index.query_batch(['find'])
for query, hits in results:
for hit in hits:
# <mark>find</mark> the needle in the haystack
markup = index.highlight(doc=doc, terms=hit['terms'])This library uses hashedindex for tokenization and indexing.
