Hi folks!
Just wanted to let you know that I released aaf 0.4.0 on last weekend.
Besides the DRb server it also includes a new lazy loading feature that
lets you do ferret searches without actually loading any records from the
DB. Useful e.g. for live searches:
model:
class MyModel
acts_as_ferret :fields => { :title => { :store => :yes }, :content
=> {} }
end
controller:
results = MyModel.find_by_contents(query, :lazy => true)
you can use the result objects as you would your AR records, if you
query any attribute not stored in the index, the whole record will be
loaded from the database. So, as long as you only access record.id and
record.title in the example, no DB call will be made.
I''ll post some more documentation about this soon. For now,
there''s some
more info about the DRb server on my blog:

cheers for new release but still got some questions about the mechanizm of aaf my task of search function has to save the tag words in table just like a_a_taggable because customer need hot tags function i wanna know how could i use database instead of file system to store index or tags -- Posted via http://www.ruby-forum.com/.

thank you jens,I saw ur reply both sides for this hot tags function that is if user search ''demo1'' with high frequency and search ''pika'' with low frequency then when we wanna make a rank for them we can know which is used high frequency for example,we can list the top ten tags but not all and i found in our aaf has some specific fields such like ferret_score,ferret_rank is that useful for this case? looking forward to ur response -- Posted via http://www.ruby-forum.com/.

These fields get set by acts_as_ferret for the results of a query - score is the score as computed by ferret, and rank the position of the result in the result set, as delivered by ferret (the order when sorting by rank may be different from the one when sorting by score if you told ferret to sort results by one or more fields). To find out the most used tags I''d probably just use the database, if you''re using acts_as_taggable or something similar this should be easy to do. Jens -- Jens Kr?mer webit!

sorry I was still gainning in the mud of search because now i create 3 table members,tags,taggings these last two tables were the nearly same as aataggable,i use them to store specific information the members table i use it for storing member information the keywords is come from the page only stored in the tag table so that mean keywords is not stored in the member fields but only in the tag table if it is in sql we found tag first then taggings then related records 1 requirement really chanllenged me just for user need display search result just like this way if it is a,b,c these 3 words then the result must be records which are satified condition 1. a and b and c first 2.then a and b, b and c, a and c--except the records are existed in above 3.the last are a, b, c--except the records are existed in above any suggestion? -- Posted via http://www.ruby-forum.com/.
