Goal

This article provides information on how to index documents which are above the document size limit.

...

Info
Configure Connector - Configure Hawksearch

Setup document size limit

Open the backend of your Sitefinity instance.
Navigate to Administartion → Settings and click Advanced (your-site-domain/Sitefinity/Administration/Settings/Advanced)
Open the Hawksearch configuration
Under document size limit enter 4000KB
Save the changes

Upload content above the limit

For the purpose of this example we are going to upload .docx, .txt and .pdf files.

Open the backend of your Sitefinity instance
Navigate to Content → Documents & Files
Upload files above the document size limit e.g. 10MB

Note
During indexing the files are stripped and only the text content is extracted. Some files contain a lot of metadata so a 10MB .pdf may only contain 1MB of actual data.

Setup search service

In order to index documents above the document size limit you need to inherit the HawksearchService class and override the AdaptDocuments. Please refer to the code snippet belowHere we will demonstrate how to remove the content field entirely or take the first 500 words in it.

Info
The following code snippet demonstrates how to strip the document from it’s Content field in order to pass the document size limit check.
