Convert media type in a migrationstep

Mon, 24 Feb 2025 08:09:00 GMT

I needed to convert the type for some media files. Suddenly webp files were sent to the CMS from an external system and webp was not added to the ExtensionString in the MediaDescriptor yet. So they ended up as generic media (MediaData), instead of an ImageFile (ImageData). There is not an out of the box … Continue reading

Best Bets, synonyms and wildcard queries

Tue, 28 Jan 2025 19:00:00 GMT

When using a wildcard in your search query like ‘search.For(query+”*”)’ or when you used the reversed method suggested in the Breaking changes article Best Bets and Synonyms will stop working/will not work as they do a lookup on the query in the request. The Best Bets can be “fixed” by using a custom IPhraseCriterion like … Continue reading

Content Definitions API Templates

Mon, 24 Apr 2023 07:00:00 GMT

With the content definitions api you can “remotely manage definitions, such as Content types, Property Groups, and Property Data Types without deploying code to the Optimizely application or using the admin user interface.” Personally, as a dinosaur, I think I will still do it the “old” way by creating content types in code, but in … Continue reading

Create Find facets based on attributes

Fri, 06 Jan 2023 08:00:00 GMT

First of all…. Happy New Year! While back I wrote a post about how to create term facets from attributes on contenttype properties. Doing a POC at the end of last year, about which I will post later, I remembered that I did not follow up on how to retrieve the facets created that way. … Continue reading

Temporarily disable the catalogitem change manager

Thu, 04 Aug 2022 07:00:00 GMT

When you run large imports you might run into the issue that the “Change log auto truncate job” will timeout because the tblActivityLog has become very large. When that happens you can manually run a stored procedure on the DB as described here. To prevent it from happening, as from EPiServer.Commerce 11.6.0, you can disable … Continue reading

Retrieve localizations through an api

Sun, 05 Jun 2022 07:00:00 GMT

When you have a need to use available localizations from e.g. a headless app, one way to do it is through a custom api. In this gist you can find a basic api controller that you could use. It uses the LocalizationService to retrieve all localizations grouped by culture, localizations with a specific key grouped … Continue reading

Imagine a scenario where you have a main catalog containing all your products and several “sub” catalogs with products linked from the main catalog.When you do a search for a product in the sub catalog and you would want to get the link to a product, you would get the link to the product within … Continue reading

Use Serilog with CMS12

Tue, 01 Feb 2022 09:00:00 GMT

In previous versions of Optimizely, when you wanted to use a different logger, it took a bit of work. Or you could use one of my providers. With CMS12 you can now just configure a different provider without the need of a custom provider. For Serilog add the following packages, I used the file sink, … Continue reading

“Filter” your commerce navigation

Mon, 29 Jun 2020 08:00:57 GMT

Within Episerver Commerce you can have a lot of rules for displaying a product to a visitor, e.g. if it’s available for the current market. So it can happen that when you click on a main category or subcategory link there are no products displayed. To prevent this, as it can be quite annoying for … Continue reading

Offload your Episerver Find tracking

Mon, 06 Jan 2020 10:00:08 GMT

Imagine a site with 10+ instances and a lot of visitors and search requests. The find queries are tracked, to provide data for the auto suggest, and cached. And then… you get an error in Find: Too Many Requests. My first thought was to increase the value for StaticallyCacheFor. But it did not have as … Continue reading

Auto correct a search query

Thu, 14 Nov 2019 10:00:44 GMT

So your visitor is in a hurry and makes a typo in the search box. Chances are no results might be returned. By using the Bing Spellcheck API you can auto correct typos in the query and, maybe, return a result. As with the auto correct on your phone, it kinda depends on how smart … Continue reading

Use ML.net recommender for recommendations (POC)

Thu, 07 Nov 2019 11:00:36 GMT

A while ago I wrote about how you can use ML.Net Recommender to add some smarts to your up-sell. I decided to take it a step further and make it work for general product recommendations. So I created a scheduled job that creates and trains the recommendation model, creates predictions for all available variations in … Continue reading

Speed up your site

Thu, 03 Oct 2019 10:00:04 GMT

When your site relies on a lot of external API’s, has a lot of JavaScript, images, Redis cache… and which site doesn’t have most of these things these days, the loading of a page might go slower than you would like, even with extensive caching. There are a few things that I found can speed … Continue reading

Use ML.net recommender for better up-sell (POC)

Thu, 13 Jun 2019 09:30:41 GMT

You may have read about ML.net by now. Among other things there is a recommendation engine. So I decided to try if it would be usable in an Commerce solution. And it is, up to a point. First I needed to get all the orders and put the products that were bought together for each … Continue reading

Remember BrilliantCut?

Tue, 30 Apr 2019 09:30:48 GMT

For a client with a huge catalog I needed something to make it easier to find their products in the back-end. Then I remembered BrilliantCut by Jonas Bergqvist, which does exactly that. As it hasn’t been updated to work with newer versions of Commerce, I forked and updated it. I also added the filter option … Continue reading

Enrich your logging with Episerver data

Fri, 15 Feb 2019 09:30:56 GMT

Some of you may have noticed I quite like Serilog. And my NuGet package to integrate it in Episerver is used quite a few times, so I guess I am not the only one. One of the reasons I like it is that you enrich your logging with a lot of extra information. There are … Continue reading

Add extra validation for a shortcut

Mon, 07 Jan 2019 09:30:51 GMT

Happy New Year everyone! Mine started out well… suddenly, without a deployment or Azure issues, a website went completely unresponsive. “502 – Web server received an invalid response while acting as a gateway or proxy server” Looking at the change log there was a content change just before the site went down. The change made … Continue reading
