filterinputs mustfilters; mustfilters &= ms.term("cityid", filterinputs.cities); mustfilters &= ms.terms("cityids", filterinputs.cities); what difference between above 2 lines? as far have tested, second allow multiple cities in document kye cityids. if matches filterinputs.cities=> record returned. while first allow once city.if matches=>record return else not. please confirm. term allows match 1 term. according documentation: the term query finds documents contain exact term specified in inverted index. see here while terms allows specify multiple terms , match of them.it works in in sql . according documentation: terms query filters documents have fields match of provided terms (not analyzed). see here

for example, have array var myarray = ['player_static.png', 'player_run0.png', 'player_run1.png', 'player_run2.png', 'player_jump0.png', 'player_jump1.png'] is there simple way "player_runx.png" images? you can use filter elements hasprefix("player_run"): let myarray = ["player_static.png", "player_run0.png", "player_run1.png", "player_run2.png", "player_jump0.png", "player_jump1.png"] let playerruns = myarray.filter{$0.hasprefix("player_run")} print(playerruns) //["player_run0.png", "player_run1.png", "player_run2.png"]

i have app grabs json file internet, parses through , creates , item object it. items have following fields: type (image, text), , data (this url if item type image or string of text if item type text) when app first loads list displays mix of items both types text , images. if item image, image displayed in list item in listview, if it's text text displayed. what need do(and having problem with) need when user selects menu "image only" show objects have type "image" in listview , hide items have type "text", if select "text only", filters out image list items , displays items of type "text". if select "all" should display default when app first loads. i not display object's type field on listview anywhere, data field of object either image loaded url or text. seems every filtering example come across when types text filters list text displayed in list , visible in list need filter not visible on list.

i trying create array can accessed of patches, seems though setting global, available in function in gave value. have following 3 segments of code in respective places: globals[a] toward top of program, in setup function have set array:from-list n-values asize [0] for integer asize defined in setup function, , go method calls function addtoarr runs following line: array:set index val for index , val defined earlier in function. might worth noting within ask patches . when run code following error: extension exception: not array: 0 error while patch 70 91 running array:set called procedure addtoarr called procedure go called button 'go-forever' i confused error, because seems me defined a array, netlogo differs in opinion. netlogo not support global arrays? appreciated.

currently developing script in jmeter, need retrieve x amount of values response push values http request, here tricky part response table changes (e.g. rows increase or decrease each time test run) far i've created regex extractor retrieves between table need create beanshell post processor retrieves values variable retrieved regex extractor , applies them http request. i'm not sure if best way open suggestions on doing way. you need beanshell preprocessor applied 2nd request, not postprocessor applied 1st request i don't think using regular expressions idea parse html, suggest going css/jquery extractor or xpath extractor instead once have required values in form of var_1=foo var_2=bar var_matchnr=2 you able add these values 2nd http request like: import java.util.iterator; import java.util.map; iterator iter = vars.getiterator(); int counter = 1; while (iter.hasnext()) { map.entry e = (map.entry)iter.next(); if (e.getvalue() != null) {

i've tried out code use loop in php add numbers seems not work, how can be? $n = 3; //or else for($i=0;$i<$n;$i++){ $n = $n+$n; } echo $n; this test code else, i'd still work, please help you increasing loop ending condition $n inside loop this means never exit loop. this infinite loop, , wont ever print anything. also loop needs $i = 0; $i < $n; $i++

i'm experimenting bit shifting using uint64 data type. code works expected when use constant number. however, fails when use variable. compiler issues "operator << cannot applied operands of type 'int' , 'ulong'" error. how go fixing code can use variable in place of constant number? here's excerpt of code using system.io; using system; class program { static void main() { uint64 x=0; int pos = 2; x = ((uint64)x | (1 << pos)); console.writeline(x); } } try making right-hand side operand of | -operator of type uint64 , e.g.: x = x | (1ul << pos); btw, 1 may prefer compound form: x |= 1ul << pos;

i using rotationanimation rotate custom view object (derived directly view ). view object's ondraw() called repeatedly during animation, , onanimationend callback called. in callback updating view's backing data object record new rotation. the problem seeing view object continues have ondraw() called after onanimationend callback has been called , has returned. problem because, in callback, update values cause view render contents rotation. since animation still transforming view, end-result briefly over-rotates before snapping correct position rotation transform removed. so, if animation causes animated view's ondraw() called after onanimationend called, how can determine when animation has really finished can update backing object model @ appropriate time? i'd grateful on this. for benefit of reading question in future, solution reliably detecting end of animation seems to override onanimationend() on view object being animated. further

i trying sort nested array of elements in asp.net , having bit of trouble. have playlist has model so: public class playlist { public playlist() { this.date = new list<dates>(); } [key] public int id { get; set; } public string userid { get; set; } public list<dates> date { get; set; } public class dates { [key] public int dates_id { get; set; } public list<places> place {get; set;} } public class places { [key] public int places_id { get; set; } public string id { get; set; } } }` as can see nested array of objects, dates, array of objects, places. what doing pulling out data so: playlist = db.playlists.where(e => e.userid.equals(userid)).orderby(q => q.id).include("date.place").tolist(); what realized places in date object wasn't being pulled out in sorted array based on place_id, rather randomly. there way pull out playlis

i have question riotgames api. have api token riot games , limited 10 requests per second. however, when want read in game info player elo + divisions, need request. in game info champion runes masteries , on, still need elo, need request server. by time have looped 10 players, have reached api limit because need general request player list , other requests each player. you error handling retry request when receive response says limit has exceeded. function request(player) response = riotgamesapi(player1) if response.status == "limit exceeded" response = request(player) else return response end end this call recursively until receive valid response

var x = ["aaa", "bbb", "ccc", ...]; function f() { var y = ["aaa", "bbb", "ccc", ...]; } it big array, @ least in opinion. i assume y gets initialized again @ every instance. would global x initialized 1 time when page loaded? seems reasonable... yes (+27 chars satisfy so!)

i working on function must create array of random boolean values , lost @ how make work inside function. on appreciated. sadly, confined rules names , how must see general structure must use, can't see how logically isn't woking. func thirdfunction() { //var numoftrue = 0 //var numoffalse = 0 var sometrue = true var randbools = [bool] () num in 1...10{ let random = arc4random_uniform(2) print(random) if (random == 0){ sometrue = false randbools.append(sometrue) } else { randbools.append(sometrue) } } print (randbools) } this works: var array: [bool] = [] func randomizer() { var bool: bool = false num in 1...10 { let random = arc4random_uniform(2) if random == 0 { bool = false } else { bool = true } array.append(bool) } print(array) }
