这里我使用 whoosh lib 进行搜索/索引.. 上部分是索引文件,下部分是演示搜索..
#indexing part
from whoosh.index import create_in
from whoosh.fields import *
import os
import stat
import time
schema = Schema(FileName=TEXT(stored=True), FilePath=TEXT(stored=True), Size=TEXT(stored=True), LastModified=TEXT(stored=True),
LastAccessed=TEXT(stored=True), CreationTime=TEXT(stored=True), Mode=TEXT(stored=True))
ix = create_in("./my_whoosh_index_dir", schema)
writer = ix.writer()
for top, dirs, files in os.walk('./my_test_dir'):
for nm in files:
fileStats = os.stat(os.path.join(top, nm))
fileInfo = {
'FileName':nm,
'FilePath':os.path.join(top, nm),
'Size' : fileStats [ stat.ST_SIZE ],
'LastModified' : time.ctime ( fileStats [ stat.ST_MTIME ] ),
'LastAccessed' : time.ctime ( fileStats [ stat.ST_ATIME ] ),
'CreationTime' : time.ctime ( fileStats [ stat.ST_CTIME ] ),
'Mode' : fileStats [ stat.ST_MODE ]
}
writer.add_document(FileName=u'%s'%fileInfo['FileName'],FilePath=u'%s'%fileInfo['FilePath'],Size=u'%s'%fileInfo['Size'],LastModified=u'%s'%fileInfo['LastModified'],LastAccessed=u'%s'%fileInfo['LastAccessed'],CreationTime=u'%s'%fileInfo['CreationTime'],Mode=u'%s'%fileInfo['Mode'])
writer.commit()
## now the seaching part
from whoosh.qparser import QueryParser
with ix.searcher() as searcher:
query = QueryParser("FileName", ix.schema).parse(u"hsbc") ## here 'hsbc' is the search term
results = searcher.search(query)
for x in results:
print x['FileName']
