Dear list,
I 'm using a text input field with autocompletion . The suggestions come
from a ferret index which is created by getting all the terms belonging to
other indices. Here is the code:
class Suggestion
attr_accessor :term
def self.index(create)
[Person, Project, Orgunit].each{|kl|
terms = self.all_terms(kl)
terms.each{|term|
suggestion = Suggestion.new
suggestion.term = term
SUGGESTION_INDEX << suggestion.to_doc
}
}
SUGGESTION_INDEX.optimize
end
def self.all_terms(klass)
reader = Index::IndexReader.new(Object.const_get(klass.name.upcase +
"_INDEX_DIR"))
terms = []
begin
reader.field_names.each {|field_name|
term_enum = reader.terms(field_name)
begin
term = term_enum.term()
if !term.nil?
if klass::SUGGESTIONABLE_FIELDS.include?(field_name)
terms << term
end
end
end while term_enum.next?
}
ensure
reader.close
end
return terms
end
def to_doc
doc = {}
doc[:term] = self.term
return doc
end
end
It works very well except that the indexing process takes a long time. Does
anybody knows if there's a better way to do this?
Is there another way to get all the terms of an index?
Thank you.
