- The cobbler's children go unshod

Now to your second question:

The Excerpt by default will be either fieldvalues (from SearchSummary, SearchText, SearchAttachment) or highlighted fields (as the above) depending on the HitSpecification.HighlightExcerpt value passed to GetResult. So if you want to change the default you need to change either:

// for field excerpts

client.Conventions.UnifiedSearchRegistry
                 .CustomizeDefaultProjection(p =>

                     p.ProjectExcerptUsing<ISearchContent>(spec =>
                             x => x.SearchTitle + " " + ..maybe another field value)
                 );

// for highlights

client.Conventions.UnifiedSearchRegistry
                .CustomizeDefaultProjection(p =>
p.ProjectHighlightedExcerptUsing<ISearchContent>(spec =>
                            x => x.SearchText.AsHighlighted(
                                new HighlightSpec { FragmentSize = spec.ExcerptLength, NumberOfFragments = 1 }) + " " + ...maybe another highlighted field)
                );   

// to compile you currently also need the following extension

public static HitProjectionBuilder ProjectExcerptUsing<T>(this HitProjectionBuilder builder, Func<HitSpecification, Expression<Func<T, string>>> sourceExpression)
        {
            return new HitProjectionBuilder(builder, projection => projection.ExcerptProjection = sourceExpression);
        }

Edited: the excerpt will be either fieldvalues or highlighted values.

I'm facing this case now. Any ideas what could be wrong and where to look for any hint?

Any ideas why excerpt is not being built correctly in my case? http://world.episerver.com/forum/developer-forum/EPiServer-Search/Thread-Container/2016/9/excerpt-being-build-incorrectly/
