Re: [platform-search-dev] Creating potential matches with new search UI

[Steffen Ryll <steffen.ryll@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi Martin,

thank you for these clarifications about potential matches.
If I understand you correctly, there's no standard possibility (through 
one of the extension points of the search plugin) to create different 
types of matches.
I have a good idea how to define the colour preference in a view 
preference. However, I didn't find out yet, how I can create matches so 
that they use my colour.

Right now, our plugin creates Match[] arrays and feeds them to 
AbstractTextSearchResult#addMatches - end of the story. I guess that it, 
somehow translates matches into markers (or annotations?) internally. 
Can I influence this translation in some way, i.e. set the colour of my 
match, have more than one match type? Does it involve defining own 
subclasses of (Text)Marker? Or rather Annotations? How could I control 
these markers?

My problem is currently that I have no clue where to start, so I'd be 
happy about good hints.

Thanks in advance,

Steffen
