solr documentation says scale function: scales values of function x such fall between mintarget , maxtarget inclusive. as example says: scale(x,1,2) values between 1 , 2 inclusive. my question is, how? if give function number 78.3 , try scale between 1 , 2, how translates 1 2 format? it go through documents in index (if read source correctly, works complete set of documents , not current result set), find minimum , maxiumum values, scale value in each document when returning between 2 provided numbers. so if have documents 0, 5, 10 , invokes scale(x, 1, 2) , should 1 , 1.5 , 2 back. the actual implementation source: return (vals.floatval(doc) - minsource) * scale + min;

i've written method checks if string in file, eclipse gives dead code warning. here method: private boolean keypresent(string key){ try{ bufferedreader filereader=new bufferedreader(new filereader(keypath)); while(true){ string s=filereader.readline(); if(s.equals(key)){ filereader.close(); return true; }else if(s==null){ filereader.close(); return false; } } }catch(ioexception e){ e.getstacktrace() return false; } } the else if(s==null) part source of warning. why? if can't find matching result(and coming outputs null), return false. think ok. wrong? and 1 more question. better use? string s; while(true){ s="new value"; .... } or while(true){ string s="new value"; ... } i think garbage collectors consume system resources, first 1 better. however, see m...

need convert unicode of soh value '\u0001' ascii. why not working? var soh = string.fromcharcode(01); returns '\u0001' or when try var soh = '\u0001' returns smiley face. how can unicode become proper soh value(a blank unprintable character) js has no ascii strings, they're intrinsically utf-16. in browser you're out of luck. if you're coding node.js you're lucky! you can use buffer transcode strings octets , manipulate binary data @ will. won't valid string out of buffer once you've messed it. either way you'll have read more here: https://mathiasbynens.be/notes/javascript-encoding or here: https://nodejs.org/api/buffer.html edit: in comment use node.js, excerpt second link above. const buf5 = buffer.from('test'); // creates buffer containing ascii bytes [74, 65, 73, 74]. to create soh character embedded in common ascii string use common escape sequence \x01 so: const bufferwithsoh...
