search

问题 I was going through the django-sphinx documentation, and it looks like it allows you to filter search results using attributes , queryset = MyModel.search.query('query') results1 = queryset.order_by('@weight', '@id', 'my_attribute') results2 = queryset.filter(my_attribute=5) results3 = queryset.filter(my_other_attribute=[5, 3,4]) results4 = queryset.exclude(my_attribute=5)[0:10] From some examples, these attributes seem to be something you specify in the sphinx configuration file, rather than

问题 Given is a list containing all but 2 numbers between 1-20 (randomly ordered). I need to find those 2 numbers. This is the (working) program I came up with: public static void main(String[] args) { int[] x= {1,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19}; ArrayList al= new ArrayList(); Map map= new HashMap(); for(int i=0;i<x.length;i++) { map.put(x[i], x[i]); } for(int i=1;i<=20;i++) { if(map.get(i)==null) al.add(i); } for(int i=0;i<al.size();i++) { System.out.println(al.get(i)); } } I would

问题 I have the following array String[] arrKey = new String[] {"A","B","C","D","E",......"Y","Z"}; I would like to search the array and give me the index of where the letter is. Say for example I want to search for the letter "E" and when I search the array it should give me the position of "E" so I should get index position 4. I don't want to do this in a loop. Is it possible? I have been looking all around and can't find an answer. 回答1: I don't want to do this in a loop. There has to be a loop

问题 I am looking to display something like: Hello, you've reached this site by looking for [google keyword(s)] I'm pretty sure I've seen this done before but I am having troubles figuring out how to grab the keywords that were used to lead a user to my site. Anyone know the answer? 回答1: You need to get the referring URL and then strip out everything for the "q" query string. This will give you the query that was used to get you to your page. 回答2: Using the referrer (http://www.netmechanic.com

问题 First I am very new to ColdFusion, but am learning pretty quickly. So I am trying to build a large database that originally displays all results with 25 lines per page and have a next/prev link to navigate through the pages. That all works fine, but when I perform a search, and when the new results display of about a couple of pages worth, the pagination links don't work. When I click on the "next" link it goes back to the original all records display. How can I fix this or what do I need to

问题 I am trying to write a utility to see if a user has logged in to windows since a date that I have stored in a database. private void bwFindDates_DoWork(object sender, DoWorkEventArgs e) { UserPrincipal u = new UserPrincipal(context); u.SamAccountName = "WebLogin*"; PrincipalSearcher ps = new PrincipalSearcher(u); var result = ps.FindAll(); foreach (WebAccess.WebLoginUsersRow usr in webAccess.WebLoginUsers) { UserPrincipal b = (UserPrincipal)result. Single((a) => a.SamAccountName == usr

问题 After a lot of reading and experimentation, it seems like I want PRIMARY strength for searching, but TERTIARY or IDENTICAL for ordering. Main question: Is that possible to achieve with H2 (or any other DB)? Secondary question: Am I the only one here or would any of you also like the above combination? Some confirmation would be helpful for my sanity. Background: It seems like the collation can only be set at the very beginning when creating the database. So I want to make sure to pick the

问题 Background : I am building a database application to store information about my massive movie collection. The listbox contains hundreds of items so I decided to implement a search feature which would highlight all items that contain a particular string. Sometimes it's hard to remember an entire movie title so I thought this would come in handy. I found this useful code on the Microsoft site that highlights all items in a listbox that contain a particular string. How can I modify it to search

问题 Is it possible to search Google for all sites built by a specific author declared by a meta author tag? eg http://www.google.com.au/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=v6J&q=%3Cmeta+name%3D%22author%22+content%3D%22Fred+Smith%22%3E&btnG=Search&meta= 回答1: Looks like the answer is no: "Google, Yahoo, and MSN do not index the <meta> author tag."

问题 I have an array as below, which has multiple columns. I want to search in the first column for a specific value, and have the rows that match returned. Is that possible to do? For example: Array ( [0] => Array ( [id] => 1 [column2] => value2 [column3] => value3 [column4] => value4 [column5] => value5 ) [1] => Array ( [id] => 1 [column2] => value2 [column3] => value3 [column4] => value4 [column5] => value5 ) [2] => Array ( [id] => 2 [column2] => value2 [column3] => value3 [column4] => value4
