FAST search - exclude property from hit highlighted summary

Question

Is it possible to control what fields are included in the hithighlightsummary using FAST Search Server? I have some custom fields, which are stored as note in the special text format. I don't want to include them in HitHighlightedSummary, but I want them to be searchable at the same time. I gave thought to this matter and found some solutions, which would be helpful.

1. This article describes how to control this feature via the managed property SummaryType parameter in the index schema. I followed all the necessary rules, reset index, made full crawling and got the same results. My custom fields were still in Summary.
2. Then I found this article, it illustrates how to exclude the unwanted fields using 'ExcludeFromSummary' managed property. This rule was described for SharePoint Search only, not for FAST. But I checked it for FAST Search too by exporting this property to FAST Search. Resetting index, full crawling....the same result. Custom fields were still in Summary.

The only information, that I have found about how HitHighlightedSummary is formed was

"By default the hit highlighted summary is configured for the body and title properties".

I checked these properties and didn't find any useful information to solve the problem. I couldn't understand, how my custom properties are displayed in the summary. May be I complicate matters and there is only one trick to hide them, isn't there?
