elasticsearch - Trouble with spaces in query to elasticsearh -

-

i'm experiencing trouble requesting fileds making requests on field spaces. mapping looks this:

"myindexname": {     "mappings": {         "mytype": {             "properties": {                 "mypropertywithspaces": {                     "type": "string",                     "analyzer": "analyzer_keyword"                 }             }         }     } }

there "analyzer_keyword" cutom analyzer keyword tokenizer , lowercase filter. when i'm sending "_analyze" request "analyzer_keyword" analyzer , query "firstword secondword" token "firstword secondword" - works expected. querystring request returns nothing if don't change space character "?" wildcard; interesting, lowercasing still works , such behaviour doesn't change if i'm telling elasticsearch use "analyzer_keyword" explicitly.

"query": { "query_string": {     "query": "firstword secondword",     "default_field": "mypropertywithspaces",     "analyzer": "analyzer_keyword" }

found solution in simple escaping space character "\ ". works correctly , prevents querystring processor injecting "and or" operators or whatever.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
