I have created a content type which is derived from out of the box page content type and I have added a site column of type publishing HTML. Now when there is less content in publishing HTML column the summary appears with search result but when there is
large content in column the hithighlighted summary comes out to be blank.
Is there any limit on number of characters in publishing HTML column to appear it in hit highlighted summary of search results.
Got confirmation after raising a ticket with MS that this is a limitation and if html publishing field contains more than 5300 characters, it won't show hit highlighted summary. The limitation doesn't apply on out of the box page content field.
