Fess Search

(from github.com/MeMeLwin)
Is it possible to display .mp4 file in Result Page in Fess when searching?
In my case, when I search for .mp4 files, the result did not show the .mp4 file.
Any setting to be done to display .mp4 files in search result page?

A filename is stored to filename field by default.

My mp4 file is too large. MaxLengthException occured. That’s why I can’t find mp4 files.
Modified the contentlength.xml and problem solved! Thank You.
