问题 I am having this weird behavior in mysql 5.6 with full text indexes I am trying to search a patients database and get the exact matches first then partials by score with a Min Score so i don't return 100000+ results just some suggestions to prevent duplicates into a EHR type of app The problem is that the exact and partial matches have the same score... Is that an expected behavior? what options do I have? 回答1: You stated that you had the same score for exact matches and partials, but your

问题 Lets say you have a list of 8 prices - for example: 1$ 2$ 3$ 4$ 5$ 6$ 7$ 8$ You want to divide the prices into 2 groups of 4 prices each. Let the total price of a group be the sum of the individual prices of the group. How do you divide the group such that the difference between the two total prices is as small as possible? The obvious solution is to try all the pairs and see which is the lowest, but is there a more efficient solution that could work if this were extended to more than 8

问题 I have a question. Imagine that in vb.net, fill a array of structure with a lot of items. For example, here I declare the structure called Persons: Public structure Persons Dim name as string Dim age as integer End structure Then, I declare a variable that is a array of persons, for make a list of friends, like this: Dim friends() as Persons friends(0).name = "Sebastian" friends(0).age = 19 friends(1).name = "Michael" friends(1).age = 34 ... So, there are any form to locate where is the

问题 I didn't find any fast algorithm for getting quad-trees differences in following format. Let's say that we have two arbitrary 4 level trees: var tree1 = [ { id: "1.1", children: [ { id: "1.1.1", children: null }, { id: "1.1.2", children: null }, { id: "1.1.3", children: [ { id: "1.1.3.1", children: null }, { id: "1.1.3.2", children: null }, { id: "1.1.3.3", children: null }, { id: "1.1.3.4", children: null } ] }, { id: "1.1.4", children: null } ] }, { id: "1.2", children: null }, { id: "1.3",

问题 I currently have a widget that will search my main textBox and highlight the words that match my search. The problem I am running into is finding a way to move the cursor to the first match found and then subsequently moving the cursor to the next match found the next time I hit enter. I have 2 ways I can search a word in my textbox. One way is to look for every match and change the font,color,size of the word being searched so it stands out from the rest of the text. Here is the function I

问题 It appears as tho the search functionality for WooCommerce products does not check "product_tag" taxonomy terms, nor SKU field? I added the SKUs as product tags to their respective products, but it still returns nothing when I search for the SKU.... How do I make the search functionality check product_tag terms? I have tried many many many things from adding tax_query to pre_get_post filter, to a whole new WP_Query loop, it just fails to search product_tags for some reason....so what is the

问题 I have a tree(RBT) consisting of N elements. Let's imagine I have this tree (N = 7): 4 2 6 1 3 5 7 How do I filter values in some range (e.g. print all values between 3 and 6) with better performance than O(N)? Is there any specific algorithm? I'm imagining it something like find position of value 3 [log(N)], somehow continue until you get to the 6 [O(M)]. 回答1: If you have Sedgevick's Algorithms, 4 ed., look at the end of chapter 3.2 on BST's. Also book companion has implementation in Java.

问题 I have a field named search_suggest having the below search_suggest: { type: "completion", analyzer: "simple", payloads: true, preserve_separators: false, preserve_position_increments: false, max_input_length: 50 } It has values indexed as { input: [ "apple iphone 6" ], output: "apple iphone 6", weight: 5, payload: { category: "mobiles" } } If I searched for apple ,It is giving me results.

问题 So I've been doing a lot of work with Tweepy and Twitter data mining, and one of the things I want to do is to be able to get all Tweets that are replies to a particular Tweet. I've seen the Search api, but I'm not sure how to use it nor how to search specifically for Tweets in reply to a specific Tweet. Anyone have any ideas? Thanks all. 回答1: user_name = "@nameofuser" replies = tweepy.Cursor(api.search, q='to:{}'.format(user_name), since_id=tweet_id, tweet_mode='extended').items() while True
