PyMongo-使用变量执行SQL'LIKE'查询

Question

The answer here applies when using PyMongo to search fields containing a search text. But only for hard-coded string values:

 db.houses.find({"hid":{"$regex": u"9"}})

So, how to shape that expression replacing that "9" with a variable?

def some_func(search_text)
    db.houses.find({"hid":{"$regex": ??????}})

Answer 1

Use re module to create a regex for your search string

import re
search_string = re.compile('9')
db.houses.find({'hid': search_string})

you can use a lot of options available in re module

Answer 2

Try this,

search_text = u"9"
db.houses.find({"hid":{"$regex": search_text }})
