Is it possible to query the index for a TermEnum for all fields in the index instead of just ? Thanks, John

Hi everybody, I need to find out all terms (field values) from one of the fields from a set of documents returned by search. In other words, I have indexed documents with two fields. I do search on one field and then want to know all other field''s values from fount documents. How? -- Sergei Serdyuk Red Leaf Software LLC web: http://redleafsoft.com -- Posted via

I need to get a set of terms being indexed using Ferret. I used IndexReader.terms and it returns a list of TermEnum nicely. The only problem is that my analyzer includes a stemming filter. So now, the terms I''m getting back are all stemmed. Is there anyway to get the original unstemmed terms back from the index somehow? Thanks. -- Posted via http://www.ruby-forum.com/.

Hey all, The frequency count returned by my ferret reader doesn''t decrement after I remove a documents with those terms. Using the example from http://ferret.davebalmain.com/api/classes/Ferret/Index/TermEnum.html the frequency increments after a document is added but stays the same after a document is deleted. index.reader.terms(:tags).each do |term, freq| "#{term} appears #{freq} times" end If I iterate through each document matched by terms_for I get the correct frequency but I assume a...

Hello, does anybody know how to implement a "Did you mean ...?" like Google with act_as_ferret? I think this is a possible way: 1. Generate a keyword-list (this is my difficulty. I don''t know how to build such a list from the index) with no stop-words from the first index. e. g. (car, ship, plant, house) 2. Build a second index from this word-list where we store the word in

...re each document contains an untokenized ''url'' field. I would like to query the index for the most popular urls. In SQL I would do this via a Group By clause. Is there anything in Ferret that will do something similar? I found this discussion that proposed a solution involving TermEnums: http://www.gossamer-threads.com/lists/lucene/java-user/32272#32272 But I noticed the IndexReader.terms and IndexReader.term_docs are not implemented. Is that solution the way to go? Would an index-only solution perform a lot faster than a pure database solution using a group by clause? Any f...

Is there a fast way to determine how many documents a term occurs in, besides iterating through every document with TermDocEnum? -- Best regards, Stian Gryt?yr

Hey .. I''m using ferret to index various objects and i''m create a Ferret::Document for each of these objects. Indexing and searching is working fine. Each of these Ferret::Documents has a ''relevance'' field, storing an integer, how relevant this object is for the search. The ''relevance'' is in the range of 1..10 Now i would like to
