search

问题 I'm working on this project where I have to search for objects in 3d space, and efficiency is a huge concern, I think Range Tree is perfect for what I'm trying to do, Interval Tree would also work but I'm not going to delete anything from the tree, once I add every object in 3D space, I'll only use the structure to do a search. Here's how I'm going to use the structure: Let say that I have an array(let's call it queryArr ) of objects (~ 10,000 objects) each objects have 3 parameter (x,y,z) I

问题 I want to implement incremental search on a list of strings. Consider I have an array containing which contains the strings store,state,stamp,crawl,crow. My application has a text box in which the user enters the search string. Now, as the user enters the text, I need to highlight all the matches. For example, when the user enters "st" I need to highlight "Store,state,stamp" now when he types "a", I need to remove "Store" from the list.I am developing the application using c# with .net

问题 Does anyone know how to use the rank by distance search option that is mentioned here? https://developers.google.com/maps/documentation/javascript/places#place_search_requests Listing this in the request options doesn't seem to work. Here's my portion of code relative to this: var request = { location: coords, //radius: 30000, keyword: ['puma, retail'], types: ['store'], rankBy: google.maps.places.RankBy.DISTANCE }; service = new google.maps.places.PlacesService(map); service.search(request,

问题 I've been wracking my brain over this but can't get it. I feel like the answer is probably obvious. What I'm trying to do is the following: I have an index controller which lists a series of Jobs which I can search using Ransack. Each job has a completion date which either has a date in it or is null (unfinished). Currently, the search itself works great. I would like to make it so that the index page loads up showing only the unfinished work, but I also want it to work so that when someone

问题 In iOS 11 Apple presented new search bar, but yet in iOS 11.2.2 developer have push\pop animation bug when both view controllers have searchController. Apple demonstrate their vision in Files app. Do someone know how do it? edit#1 Question with broken animation.

问题 Is there any way to programmatically search GMail, preferably using C#? For example, I'd like to get all email messages matching the search label:MyLabel from:no_reply@foo.bar , so that I can parse the email bodies as required. The only thing remotely feasible I've found is the GMail API by Johnvey Hwang, though it doesn't look like it supports searching email and also hasn't been updated in many years either. In any case, I haven't had much luck in getting it to even connect to my account so

问题 I have the following table Cities: ID(int),City(char),latitude(float),longitude(float). Now based on a user`s longitude(ex:44.8) and latitude(ex:46.3) I want to search for all the cities near him within 100 miles/KM. I have found some examples but don`t know how to adapt them to my case select * from GEO.Cities a where SDO_WITHIN_DISTANCE([I don`t know], MDSYS.SDO_GEOMETRY(2001, 8307, MDSYS.SDO_POINT_TYPE(44.8,46.3, NULL) ,NULL, NULL), 'distance = 1000') = 'TRUE'; Any help would be

问题 Is the greedy best-first search algorithm different from the best-first search algorithm? The wiki page has a separate paragraph about Greedy BFS but it's a little unclear. My understanding is that Greedy BFS is just BFS where the "best node from OPEN" in wikipedia's algorithm is a heuristic function one calculates for a node. So implementing this: OPEN = [initial state] CLOSED = [] while OPEN is not empty do 1. Remove the best node from OPEN, call it n, add it to CLOSED. 2. If n is the goal

问题 I have a recursive function kindly explained to me by @thothal here This allows me to recursively get dataframes based on looking up a character string in the parent dataframe. With the example I provided this works great. However I am now working on further tables where the elements in the child are present in the parent and vice versa. This leads to an infinte loop in the recursive function. To repeat the original question with changes: Numsdf1<-c("C123","C456","C789") Textdf1<-c("Harry",

问题 I'm trying to implement search functionality in my app, which is very basic at the moment. When I press the search button on my Nexus, the search intent seems to not fire because neither onCreate() nor onNewIntent() gets called. I have basically copied the whole example you can find on Android developers, but it is still not working.
