Sorry for the late response.

Nice this is exactly what I wanted. However when I started to look at the actual results I'm confused. For my example of searching for "list" here is the first result:


FCL units reference	tfpobjectlist.html
Return the first non-nil object in the list

What is this exactly? I expected to get results like from https://docs.getlazarus.org where it would say this is a class or a method etc... and a description of the class. I had been using their API (Anthony is responsible for the project I think) but its got bugs and I haven't been able to contact the developer to fix them.

What if I want to see the reference for TStringList? If I enter that term I get lots of results but all I have to go on is the "context" which doesn't really tell me what the result is how to filter it.
