If we want to delete existing content from the index store, DNN Reindexing helps perform the same.

As part of our Server Management Services, we assist our customers with several DNN queries.

Today, let’s see how our Support Engineers do this for our customers.

About DNN reindexing and crawling

Before getting detailed into the error let’s discuss reindexing and crawling.

Crawling is the method to automatically discover and scan websites. This is done by analyzing the links from one webpage to another.

Search crawlers do reindex as part of their scheduled tasks. However, sometimes reindexing the crawlers will throw tricky errors.

Let’s now see how our Support Engineers fix an error in such a case.

How we do DNN reindexing crawling?

Having a decade of experience in managing servers, our Dedicated Engineers are familiar with DNN errors.

Recently, one of our customers was using DNN 7.2 and his site crawler was not indexing properly.

On checking the schedule history, it showed the below content.

Search: Site Crawler Starting. Content change start time x/xx/xxxx

Tabs Indexed: 0
Modules (Metadata) Indexed: 0
Modules (Content) Indexed: 0
Users Indexed: 0
Total Items Indexed: 0
Indexing Successful

In a detailed analysis, we found that the DNN site used the Lucene search engine.

It is a file-based type of search engine. And, this caused the error.

In order to resolve the error, our Support Engineers followed the below steps.

• Firstly, we took the backup of the site.
• Then, we deleted all the files in the folder C:\Inetpub\vhosts\domain.com\httpdocs\App_Data\Search
• We then clicked the button under Admin > Search Admin > Re-Index.
• Then, Host > Scheduler > Site Crawler to RUN status.
