🚀 go-pugleaf

I would like to write DA or an application which will be a specialized
dictionary. The key might require a 2 bytes per character (it is a
specialized alphabet - glyphs). It will have approx 300,000 entries and
for each key there might be up to a page of text. I would like to be 
fairly fast and there might be a cross-indexing from the text.
I would appreciate any help in pointing me in the right direction in
terms of algorithms and if there is any public C-source that could could
be obtained as a starting point.
      Many thanks    wb
