Dear all, It seems there''s a sort bug with ferret 0.10.9 on Debian. I sort the search results by a field which can contain null values. The string sort type doesn''t work. If I test the values and replace null by empty strings when indexing, it works.

Dear all, Does anybody know if there''s problem with ferret running with mongrel ? I got unpredictable segfaults. Everything works well with fastcgi instead of mongrel. I use ruby 1.8.5, apache 2, mod proxy, mongrel 0.3.13.4, ferret 0.10.13 and rails 1.1.6 Thanks, Johan Johan Duflost Analyst Programmer Belgian Biodiversity Platform ( http://www.biodiversity.be) Belgian Federal

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 =

Hi, We''re using Ferret 0.9.4 and we''ve observed the following behavior. Searching for ''fieldname: foo and bar'' works fine while ''fieldname: "foo and bar"'' doesn''t return any results. Is there a way to make ferret recognize the ''and'' inside the query as a search term and not an operator? (I hope I got the

I am using the tm package to do text miniing: I have a huge list of stopwords (2000+) that are in a csv file. I read it as follows: stopwordlist <- read.csv("stopwords to be Removed 10042011.csv") myStopwords <- as.character(stopwordlist$stopwords) When try removing the stopwords using tr1=tm_map(tr1,removeWords,myStopwords) I am getting the following error: Error in

Hi, I do not understand the stopword function... I've set the termgenerator like this: $self->{'Stemmer'} = new Search::Xapian::Stem(german2); $self->{'Stopper'} = new Search::Xapian::SimpleStopper(); $self->{'TermGenerator'} = new Search::Xapian::TermGenerator; $self->{'TermGenerator'}->set_stemmer( $self->{'Stemmer'} );

Hi! I would like to use the lists of stopwords provided with Xapian. Are there some standard way to remove stopwords automatically, or should I implement it mysel in the indexer? Regards, Georges Dupret

I''m trying to search a Model by the state field using Acts As Ferret. The query for this is ''+state:NY'' (substitute state abbreviation for NY). This works find however ''+state:OR'' returns nothing, though just ''portland'' will pull up matches within that state. I''m pretty sure it''s reading OR as an or conditional

I am seeing trouble with searches for ''you'' not returning anything. It appears that ''you'' is a stop word to the standard analyzer: require ''rubygems'' require ''ferret'' index = Ferret::I.new(:or_default => false) index << ''you'' puts index.search(''you'') returns

I am using code that previously worked to remove stopwords using package "tm". Even manually adding "the" to the list does not work to remove "the". This package has undergone extensive redevelopment with changes to the function syntax, so perhaps I am just missing something. Please see my simple example, output, and sessionInfo() below. Thanks!

I'm looking at adding some stopwords to my indexing procedure, and was wondering if anyone had any good rules of thumb on how to pick which words to blacklist. It all seems a little... well... vague. Although I guess it kind of depends on the sort of documents you're wanting to index. My current idea is to write a little script to output the terms with the highest frequency in my

Buenos días, Estoy realizando un análisis de topic models con el método LDA. En principio, he quitado del análisis las palabras "stopwords" universales. A la hora de ver los topics y sus palabras más frecuentes encuentro que son muy similares y hay palabras que aparecen en todos los topics. Los textos que estoy analizando son opiniones de consumidores sobre una categoría concreta de

Hola, Acabo de calcular tf-idf y me surge una duda. ¿Habría un valor de idf o tf-idf que se considerara como umbral para establecer que una palabra es muy común o no? Los valores de idf en mis datos van entre 0 y 3.78 y los de tf-idf ente 0 y 0.07.

Hi, I just started using ferret and the aaf plugin and it seems to work quite nicely. However, my fields are very short (titles of music) and I don''t think may users will be typing in apostrophes when they are looking for something. Right now, for a simple document such as "what i''ve done" I''d like it to be indexed as "what ive done" instead. Right

Hi, We are currently testing Asterisk with Wildcard 100XP and serveral Cisco ATA Box. Everything works great except that the card does not detect the hangup signal. We are using a standard Belgian PSTN line. I have not found anything about a be zone (only us, fr, de, nl, ...). Does someone experience the same problem? Do I need to create a new zone be (and how to do that)? Another small
