检查列表中是否有任何单词出现在字符串python中

Question

I have nearly 50k documents in a mongo collection somewhat like this:

{"title":"sample title sample title",
 "content":"test content test content",
 "reply":{
           "replyContent":"sample reply content test"
          }
}

and I have an array of words something like this:

wordArr = ["sample","test"]

I need to match if any word form wordArr present in my collection of document. I have to iterate over each document from the collection and have to search if any of the word given in array id present in either of the fields ie title , content and replyContent

Answer 1

The following should work assuming your mongo collection is in a dictionary (sorry I have no experience with mongo collections.

dict = {"title":"sample title sample title",
        "content":"test content test content",
        "reply":{"replyContent":"sample reply content test"}
       }

wordArr = ["sample","test"]

for word in wordArr:

    for key, value in dict.iteritems():

        if word in value:
            print 'Word: `%s` present in `%s`: %s' % (word, key, value)

        if key=='reply':
            for key2,value2 in value.iteritems():
                print 'Word `%s` present in `%s`: %s' % (word, key2, value2)

This will give you the following output:

> python test.py
Word `sample` present in `replyContent`: sample reply content test
Word: `sample` present in `title`: sample title sample title
Word: `test` present in `content`: test content test content
Word `test` present in `replyContent`: sample reply content test

Answer 2

If you just want to return True or False:

d = {"title": "sample title sample title",
     "content": "test content test content",
     "reply": {
         "replyContent": "sample reply content test"
     }
     }

word_set = {"sample", "test"}
def is_present(d, st):
    for v in d.values():
        if isinstance(v, dict):
            for val in d.values():
                if any(word in st for s in val for word in s.split()):
                    return True
        else:
            if any(word in word_set for word in v.split()):
                return True
    return False

print(is_present(d,word_set))

If you have arbitrary levels of nesting you might need a nested approach
