问题描述
下面的查询是我想使用elasticsearch-dsl-py构造的，但是我不知道该怎么做。
GET /my_index/_search
{
"query": {
"filtered": {
"filter": {
"bool": {
"should": [
{
"term": {
"status": "a"
},"term": {
"status": "b"
},"term": {
"status": "c"
}
}
]
}
}
}
}
}
select * from my_index where status in ("a","b","c")
使用elasticsearch-dsl-py，它与我所能接近的很近，但是并不相同。
class MyIndex(Document):
status = Keyword() / Text()
MyIndex.search().filter('should',status=["a","c"])
解决方法
执行此操作的另一种方法是对数组使用package com.bigfamilydevelopers.saverforall.activity;
public class SplashScreen extends AppCompatActivity {
SplashScreen activity;
Context context;
AppUpdateManager appUpdateManager;
AppLangSessionManager appLangSessionManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
context = activity = this;
appUpdateManager = AppUpdateManagerFactory.create(context);
appLangSessionManager = new AppLangSessionManager(activity);
UpdateApp();
setLocale(appLangSessionManager.getLanguage());
}
@Override
protected void onResume() {
super.onResume();
activity = this;
appLangSessionManager = new AppLangSessionManager(activity);
appUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() == UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
try {
appUpdateManager.startUpdateFlowForResult(
appUpdateInfo,IMMEDIATE,activity,101);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
});
}
public void HomeScreen() {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent i = new Intent(SplashScreen.this,MainActivity.class);
startActivity(i);
}
},1000);
}
public void UpdateApp() {
try {
Task<AppUpdateInfo> appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();
appUpdateInfoTask.addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
&& appUpdateInfo.isUpdateTypeAllowed(IMMEDIATE)) {
try {
appUpdateManager.startUpdateFlowForResult(
appUpdateInfo,101);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
} else {
HomeScreen();
}
}).addOnFailureListener(e -> {
e.printStackTrace();
HomeScreen();
});
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == 101) {
if (resultCode != RESULT_OK) {
HomeScreen();
} else {
HomeScreen();
}
}
}
public void setLocale(String lang) {
if (lang.equals("")){
lang="en";
}
Locale myLocale = new Locale(lang);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf,dm);
}
}
查询，因为每个数组元素都被隐式或。另外，我不确定您正在运行哪个版本的ES，但是很早以前就知道filtered has been replaced by bool在版本5中。因此，您的查询可以这样重写：
terms使用GET /my_index/_search
{
"query": {
"bool": {
"filter": {
"terms": {
"status": ["a","b","c"]
}
}
}
}
}
表示：
