Algolia Search Facet geolocation - algolia

We are running a Magento Shop and we want to display products in the customers region. How can we achive this as a facet, like price range? Only that we take the distance as a range.
For a logged in customer we could use the customer-address as a reference point. For guests we could use the IP as a fallback.

If your records are geo-localized (have a _geoloc: { lat: XXX, lng: YYY} attribute; yes you can definitely use the geo-search feature to restrict the search to results that are "close to them" (using aroundRadius and aroundLatLngViaIP for instance).
That being said, maybe you want more control/precision -> so if you are able to filter the results based on a facet value, it would work as well. You'll need to enforce the filter on the underlying AlgoliaSearchHelper in the JS code using addFacetRefinement.

Partially matching a post code with Algolia

I've loaded a dataset into an Algolia search index. Each item in the index is a shop with a catchment area (the catchment area is just an array of UK Postcodes that a store covers). For example:
['DS4 6','DS4 7', 'DS5 8, 'DS6 9' ... ]
The search feature is working to a point. If people search for "DS4" then Algolia returns several stores, but most people are typing their full post code (for example DS4 8XX) and this isn't returning anything even though "DS4" is indexed several times.
Is there a configuration in Algolia to search for the first part of a word, even when a person has 'typed past it'?
To clarify this a bit further. I could store every single individual postcode in a catchment area but there are millions and millions of them. A full UK postcode would be "DS4 7EN", so there are two more characters on the end representing a street in the UK. I've got the first part of a postcode: eg "DS4 7" because it seems excessive to store everything when I only really care about the wider area, ie: DS4, DS5, CV43, AB2 (and so on).
I could also probably use a places api and geocode the address. But I already have this catchment area postcode data, so it seems a shame not to use it if I can.
Algolia, like most search engines supports prefix search in order to allow search-as-you-type results, which is leveraged with InstantSearch libraries, where results are updated live as the user types. Without prefix search, you would have to wait for the user to enter an entire word before displaying any meaningful result.
In your case, since the catchment areas are indexed, e.g., DS4 6, when a user types DS4 6XX, no records will match the query since the query acts as a filter on the records based on their searchable attributes.
That said, I see two possible workaround that you can implement.
The first solution is to use the removeWordsIfNoResults index setting and set it to "Last Word". This will remove the last word of the query if there are no results. For instance, with the query DS4 6XX it will remove 6XX to just keep DS4 and retrieve the items that match this query. Note that this solution relies on the fact that DS4 6XX has two words (separated by a space) and it won't work with DS46XX.
The second solution is to change the structure of the records to add the full postcode in each item of the index. Since these are shops, I believe that it should be possible. This way your users will be able to search for both the full postcode DS4 6XX and the catchment areas DS4 6. Unless I misunderstood your problem, I don't see the need to store the full list of postcodes associated to a catchment area.

Dynamics 365 c# plugin: filtering a lookup fields data

Good evening,
I'm currently working on a plugin that needs to filter a lookup field data returned based on an option set selected value. IE:
Option Set: Automobile Type: Car , Truck or Motorcycle, the lookup field data needs to be filtered by the option set selected. Car: then the lookup field will only display car models or truck is selected then the lookup field will only display truck models ... ...
Any help would be greatly appreciated. I need to keep away from Javascript if possible..
Thanks
Sal
Although is possible to implement the logic with a plugin, in your case I strongly suggest to change the initial option set to a lookup, in this way you can leverage the built-in filtered lookup offered by the platform.

Demandware: Find Product's Category Position?

I'm updating a data feed export, which links a Product to a given Category. I want to also include that product's merchandising position within that category, which currently exists in Business Manger, and is used to control sorting on Product listing pages:
I'm digging through the API docs, and the logical place for this information to be exposed in in dw.catalog.CategoryAssignment, but it's not there. I'm currently inferring the position by essentially doing this:
// assume var product, category
var position = category.products.firstIndex(p => p.ID == product.ID);
However, this tells me where the Product got sorted to, not what the actual Position value is within Demandware. It works for now as an expedient hack, but I really want to replace it with something that pulls the actual value from DW.
Where in the Commerce Cloud API can I find the merchandising position for a given Product in a given Category?
I think you would'nt get the actual position of the product index as you may have multiple sorting rules to display different outputs on the category listing pages. These sorting rules can be created as and when required based on certain rules. I don't think this can be reflected on the product feed.
It took some digging, but I managed to find that the "Position" field for Products in the BM is stored as Product.searchPlacement. To find it, you have to look in Category.products, find the Product you want, and grab the searchPlacement property of that product.
In effect, I used:
// assume var product, category
var position = category.products.find(p => p.ID == product.ID).searchPlacement;
For Products that don't have a Position assigned in the Business Manager, searchPlacement is 0. Otherwise, it reflects the value entered in the BM.

Getting Streets of a specific postcode using Open Street Maps

I want to write a code that has the Countrycode and Postcode as an input and the ouput are the streets that are in the given postcode using some apis that use GSM.
My tactic is as follows:
I need to get the relation Id of the district. For Example 1991416 is the relation id for the third district in Vienna - Austria. It's provided by the nominatim api: http://nominatim.openstreetmap.org/details.php?place_id=158947085
Put the id in this api url: http://polygons.openstreetmap.fr/get_wkt.py?id=1991416&params=0
After downloading the polygon I can put the gathered polygon in this query on the overpass api
(
way
(poly: "polygone data")
["highway"~"^(primary|secondary|tertiary|residential)$"]
["name"];
);
out geom;
And this gives me the streets of the searched district. My two problems with this solution are
1. that it takes quite a time, because asking three different APIs per request isn't that easy on ressources and
2. I don't know how to gather the relation Id from step one automatically. When I enter a Nominatim query like http:// nominatim.openstreetmap.org/search?format=json&country=austria&postalcode=1030 I just get various point in the district, but not the relation id of the searched district in order to get the desired polygone.
So my questions are if someone can tell my how I can get the relation_Id in order to do the mentioned workflow or if there is another, maybe better way to work this issue out.
Thank you for your help!
Best Regards
Daniel
You can simplify your approach quite a bit, down to a single Overpass API call, assuming you define some relevant tags to match the relation in question. In particular, you don't have to resort to using poly at all, i.e. there's no need to convert a relation to a list of lat/lon pairs. Nowadays the concept of an area can be used instead to query for certain objects in a polygon defined by a way or relation. Please check out the documentation for more details on areas.
To get the matching area for relation 1991416, I have used postal_code=1030 and boundary=administrative as filter criteria. Using that area you can then search for ways in this specific polygon:
//uncomment the following line, if you need csv output
//[out:csv(::id, ::type, name)];
//adjust area to your needs, filter critera are the same as for relations
area[postal_code=1030][boundary=administrative]->.a;
// Alternative: {{geocodeArea:name}} -> see
// http://wiki.openstreetmap.org/wiki/Overpass_turbo/Extended_Overpass_Queries
way(area.a)["highway"~"^(primary|secondary|tertiary|residential)$"]["name"];
(._;>;);out meta;
// just for checking if we're looking at the right area
rel(pivot.a);out geom;
Try it on overpass turbo link: http://overpass-turbo.eu/s/6uN
Note: not all ways/relations have a corresponding area, i.e. some area generation rules apply (see wiki page above). For your particular use case you should be ok, however.

How to order documents by a dynamic property in Mongoid

I am using Mongoid to store a series of geocoded listings. These listings need to be sorted by price and proximity. The price of every listing is a field in the database whereas distance is a dynamic property that is unique for every user.
class Listing
include Mongoid::Document
field :price
def distance
get_distance(current_user.location,coordinates)
end
end
How can I sort these documents by distance? I tried #listing.desc(:distance) and that didn't work.
The short (and unhelpful) answer is: you can't.
Mongoid does have the ability to query based on 2d co-ordinates though, then you could update your controller to do something like this:
#listings = Listing.near(current_user.location)
Which I believe will return your listings in order of distance.
On a side note, I noticed that your Listing model is referring to your current_user object, which kinda breaks the MVC architecture, since your models shouldn't know anything about the current session.
