Make sure you have correct configuration in front-end website\Configs\Mediachase.search.config. Sounds like the path for saving the index data was wrong.

Hi Quan,

   When you say front end, can you please detail more?

We have Episerver website and commerce website which are hosted seperately.  Both has Mediachase configs in the configs folder.

Both are configured to use basepath 

For Commerece as shown below 

<Indexers basePath="[appDataPath]\Search\ECApplication\">
    <add name="catalog" type="Mediachase.Search.Extensions.Indexers.CatalogIndexBuilder, Mediachase.Search.Extensions" />
</Indexers>

However, the episerver one is configured to a different path, now when I serach something on commerce catalog from episerver UI, the error is thrown showing the path is not found though I am searching catalogs.

Thanks,

Rams

It's the CMS site, some people refer it as front-end site, as opposed with backend/Commerce Manager.

What is the appDataPath for your CMS site? 

@Rams: For an example of config setup, see: https://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2018/1/issue-with-catalog-search/

@Quan the app path for the CMS is the one tha is erroring. Which is shown on the intial post.

@Mari, Thanks for stepping in, will give it a go.

Thanks,

Rams

I think I understand the problem now. because you have two different paths for CMS and Commerce Manager, so there was no index for CMS site to use. best practice is usually to have them point to a shared path. Otherwise you would need to run the "Full Search Index" job to index on CMS site.
