FAQ

Where to ask my questions?

How can I make the indexing faster?

Currently, Picky uses as default a partial index (for * Queries, like “Yukihiro Matsu*”) a generator Partial::Subtoken.new( :down_to => 1 ), which means that you will get a result when searching for:

  • “Yukihiro Matsumoto” (from the exact index)
  • “Yukihiro Matsumot” (from here on from the partial index)
  • “Yukihiro Matsumo”
  • “Yukihiro Matsum”
  • “Yukihiro Matsu”
  • “Yukihiro Mats”
  • “Yukihiro Mat”
  • “Yukihiro Ma”
  • “Yukihiro M”

It is very intensive, generating an index for all subtokens of e.g. Matsumoto.
If you don’t need that, use a partial generator that just goes down 3 characters:
field(:title, :partial => Partial::Subtoken.new(:down_to => -3))
Like this you find:

  • “Yukihiro Matsumot”
  • “Yukihiro Matsumo”
  • “Yukihiro Matsum”

Or absolute, one that goes down to the e.g. fourth character:
field(:title, :partial => Partial::Subtoken.new(:down_to => 4))

Hope that helps!
