Today I’d faced a trivial problem but finally easy to solve, the problem was the following:
A customer uploads in a SharePoint document library several images files as jpg, png, etc… but he was complaining about that files in the document library were not indexed.
First I took a view to the search logs and apparently all was correctly, then I pointed the root cause to index file types in Search Service App, and boom, jpg files and png files were not included in Search.
After I included these two files types, all the items were indexed, but I realized that png files were not indexed at all, and these kind of files were launching in the search the following error:
So… what we can do? We already added the file type to Search, so next step? Easy answer… Powershell!!
Is rare to develop a custom iFilter, but the next step will help to make this:
We need to run the New-SPEnterpriseSearchFileFormat cmdlet, this adds a new file format and a corresponding file name extension to the search parsing system, so, let’s powershelling
$ssa = Get-SPEnterpriseSearchServiceApplication “Enterprise Search App”
New-SPEnterpriseSearchFileFormat –SearchApplication $ssa –FormatId png –FormatName PNGFiles –MimeType application/png
After registering the file format, restart the search service and launch a full crawl
Hope it helps!
