Whoosh is a text indexing software (the core indexing part of a search engine), written in 100% Python (so it's easy to install and use on any platform where python is available).



#make index for your search 
import os.path
from whoosh.index import create_in
from whoosh.fields import Schema, TEXT
from whoosh.index import open_dir

from whoosh.fields import Schema, STORED, ID, KEYWORD, TEXT
schema = Schema(title=TEXT(stored=True), content=TEXT(stored=True))

if not os.path.exists("index"):
    os.mkdir("index")
ix = create_in("index", schema) #only do this once

ix = open_dir("index")

writer =  ix.writer()
f = open("vulgar.txt").read().decode("utf-8")
writer.add_document(title=u"Vulgar", content=f)
f = open("liz.txt").read().decode("utf-8")
writer.add_document(title=u"liz", content=f)
writer.commit()
#search your index
import os.path
from whoosh.index import open_dir

if not os.path.exists("index"):
    os.mkdir("index")
ix = open_dir("index")

searcher = ix.searcher()

from whoosh.qparser import QueryParser
parser = QueryParser("content", ix.schema)
q = parser.parse(u"love monkey")

r = searcher.search(q)

print "searching ", ix.doc_count()
for hit in r:
    print (hit["title"], hit.highlights("content")) #sq brackets dict/lists
