SharePoint 2013 Search
I created an BCS external content type and crawl it. In the search result page, I use the default display template to show the BCS results. But only Title and URL are showed in the result page, no HitHighlightedSummary text between the Title line and URL line.
In IE Developer debug mode, I can see HitHighlightedSummary property in ctx but it's just empty. For the normal SharePoint content, the HitHighlightedSummary field is showed fine. I am wondering why...?
I have tried recreated the Search Service Application but got the same result.
In some threads, I read that in FAST Search for SP2010, we can control if a managd property is to be included in the hithighlightedsummary text.
Manage hit highlighted summary for a managed property by using Windows PowerShell (FAST Search Server 2010 for SharePoint)
In SP2013 Search, it seems that we can't control it though...
I excluded some fields that has "<" or ">" from the managed properties. Then the HitHighlightedSummary appears now. Problem is resolved.
This issue appears again even if I remove characters like "<" ">". There is nothing in HitHighlightedSummary field when all the table columns just contain normal text...
Any body knows about how the index works for this HitHighlightedSummary property?
I also wanted to have the option to choose on which managed property a dynamic teaser will be created.
The official response that I received from Microsoft that it is not possible any more.
HitHighlightedSummary is generated only from body managed property.
I made some further tests and Here is what I found:
1. If I remove all the mapped managed property for these table columns, the text would appear in the HitHighlightedSummary field.
2. If I create and map a managed property to it ("Search", "Queryable" and "Retrievable"), then it became empty once again.
I am doing some detailed test to see what the heck cause it is.
