Content Enrichment input/output properties limitation

Question

Any body know: What's the count limitation of content enrichment configuration output properties?
In content enrichment configuration of Search Service Application, I use a database query to get all the product attributes and configure them to be output properties. When I assign 2500 properties to it, the crawling process just doesn't call the content
enrichment web service at all. If I try "top 300 attributename..", it works. Is there anybody know the limitation here?
##...Get all product attributes from database and then insert them into a System.Collections.Generic.List[System.String] $attrList.
$config.OutputProperties = $attrList;
Set-SPEnterpriseSearchContentEnrichmentConfiguration -SearchApplication $ssa -ContentEnrichmentConfiguration $config

Answer 1

The web service call may just be timing out.  You can try increasing the timeout.  However, I would heavily evaluate whether you need to return that many properties as the performance implications are huge.
