node.js - Nominatim retrieving different data for the same request -


i'm using nominatim api bounding boxes , polygon points of local streets project.

an issue found when request url on web browser, example:

rua de santa maria

it retrieves bounding boxes:

["32.6474594","32.64779","-16.8998967","-16.8993021"] ["32.6469257","32.6470059","-16.8981943","-16.8974107"] ["32.6478793","32.6478838","-16.9007069","-16.9005973"] ["32.6478902","32.647988","-16.9014895","-16.9007494"]

but when use same url request using node.js application:

var request = require('request');  var url = encodeuri("http://nominatim.openstreetmap.org/search?" +      "q=rua de santa maria,madeira&format=json&polygon=1&addressdetails=1");  request({url: url, json: true}, function (err, res, json){     console.log(json); });

it retrieves:

["32.6470059","32.647067","-16.8984633","-16.8981943"] ["32.6469257","32.6470059","-16.8981943","-16.8974107"] ["32.6480316","32.6480782","-16.9021559","-16.901742"] ["32.6478793","32.6478838","-16.9007069","-16.9005973"]

which different. polygon points retrieved different. has idea why happens?

the requests not same. browser sends additional information in request headers such preferred language. these additional information seem influence search result.

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
