How to perform a wildcard search in Lucene

阅读更多关于 How to perform a wildcard search in Lucene

问题 I know that Lucene has extensive support for wildcard searches and I know you can search for things like: Stackover* (which will return Stackoverflow ) That said, my users aren't interested in learning a query syntax. Can Lucene perform this type of wildcard search using an out-of-box Analyzer? Or should I append "*" to every search query? 回答1: Doing this with string manipulations is tricky to get right, especially since the QueryParser supports boosting, phrases, etc. You could use a

PHP PDO LIKE : escaping the % character when combining with wildcard

阅读更多关于 PHP PDO LIKE : escaping the % character when combining with wildcard

问题 $percent = ‘%’; $st=$db->prepare(“SELECT * FROM x WHERE y LIKE ?”); $st=$st->execute(array(‘%’.$percent.’%’)); /*I want to get all records with the string % included like 5% etc.*/ The above example will not match correctly, instead matching all records in table x. In order for this to work correctly, I apparently need to set $percent='\%'. This is where I am left confused about the concept behind prepared statements. I thought the whole point of prepared statements was that the value itself(

Why/how does named vs wildcard import affect parameters?

阅读更多关于 Why/how does named vs wildcard import affect parameters?

So... I'm tinkering with some basic python/tkinter programs, and translating the code from python 2.x in the book I'm reading, to 3.x to make sure I understand everything. I was also attempting to write the code with 'proper' named imports instead of wild card import i.e. from tkinter import * but its not working out so well... What has me baffled at the moment is this: the original code does a wildcard import of tkinter, and seems to be able to 'get away with' not using quotes around parameter variables like sticky=W , while if I do a named import I have to use quotes around the 'W' or I get

Incompatible types when using upper bounding wildcard

阅读更多关于 Incompatible types when using upper bounding wildcard

问题 I'm really confused of how upper bounded types work in Java generics. Let's say I have interface IModel<T> interface I class A implements I class B implements I class C implements I then I have a method with parameter as follows foo(IModel<Map<? extends I, Map<? extends I, List<? extends I>>>> dataModel) calling that method like IModel<Map<A, Map<B, List<C>>>> model = ... foo(model) ends with compilation error Error:(112, 49) java: incompatible types: IModel<java.util.Map<A,java.util.Map<B

A batch file that copies another into Start Up folder?

阅读更多关于 A batch file that copies another into Start Up folder?

I am making a batch file that needs to copy another batch file into the Start Menu Start Up folder (the one used when a program launches on login/start up) . Since the path uses the user's computer name eg. C:\Documents and Settings\User Name I need the batch file to get the user's correct name instead of the "User Name" or * (wildcard). Wildcards doesn't work as the batch file comes up with " the filename directory name or volume label syntax is incorrect ". I hope this is clear enough. zask You can also try this: cd %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup It works in Windows

Java string matching with wildcards

阅读更多关于 Java string matching with wildcards

I have a pattern string with a wild card say X (E.g.: abc*). Also I have a set of strings which I have to match against the given pattern. E.g.: abf - false abc_fgh - true abcgafa - true fgabcafa - false I tried using regex for the same, it didn't work. Here is my code String pattern = "abc*"; String str = "abcdef"; Pattern regex = Pattern.compile(pattern); return regex.matcher(str).matches(); This returns false Is there any other way to make this work? Thanks Just use bash style pattern to Java style pattern converter: public static void main(String[] args) { String patternString =

What's the best way to checkout selected files and folders from a bare git repository on linux?

阅读更多关于 What's the best way to checkout selected files and folders from a bare git repository on linux?

I'm setting up a git repository for a website on a GoDaddy shared hosting account. Normally one would set up a git bare repo on the server that contained the live web data only, then on a push to the remote use a git post-receive hook to checkout to the live directory (thanks to @VonC for the links). That's fine, but I've set up the repository to include work files as well. On the server I have, /home/username/repo.git/work_folders, and /home/username/repo/web_files_and_folders for the repository, and, /home/username/public_html/web_files_and_folders for the live files and folders. The work
