Lucene 6.2 and ISO-8859-1 (latin) characters -


i'm trying lucene index searcher on project.

the content of documents indexed have latin (iso-8859-1) characters, users can (and will) search using charset.

as far know, lucene generates index files using utf-8.

questions:

1) there way specify charset when searching lucene? or have manually convert query utf-8 , run search?

2) indexsearcher.search() method not ignoring whitespaces, have guess "tokens" right meaningful results show up. if user forgets add whitespaces on searched term, no results showed. there way configure searcher (or queryparser) ignore whitespaces?

  1. not quite sure running trouble here. presume reading user input string, i'm don't know issue come up. providing code clarify that. if are, indeed, reading byte array user input, yes, converting necessary. it's not laborious process convert byte[] string though. use string ctor.

  2. queryparser tokenizes @ whitespace if analyzer have passed it does. standardanalyzer typical choice.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
