Subject: [Ferret-talk] Find results that some (but not all) of search term
	words
Message-ID: <14749d7ead34e3a601c4f7ba5eb8b6c5@ruby-forum.com>

That title's not great sorry.  Anyway - let's say i've indexed 3 records
that have these name fields:

St Joseph's Primary
St Mark' Primary
St Mary's Secondary School

And my search term is "St Joseph's Primary School"

How can i do my search so that "St Joseph's Primary" is the top result?
I tried splitting the name with 'OR', like this (i'm using
acts_as_ferret in rails)

School.find_with_ferret(school.name.gsub(" OR "))

But this returned me all of the records (no problem), but with St
Joseph's Primary not being the top result (not good enough).  Since my
required record is the closest match (intuitively) i feel like i should
be able to get it as the top result.

Can anyone help?

Thanks
max

Hi Max,

what is the order of the results you get? I'm suspecting this could be
due to the behaviour of the tokenizer, the other results might be a
clue.  You could also browse the index using ferret-browser to see how
it's been tokenized.

John.

Subject: [Ferret-talk] SortField via Drb
Message-ID: <1221054200.5888.30.camel@dogen.thepride.>

Hi,

we need to use an SortField object so we can specify the column type:

sf_title = SortField.new(:title, :type => :string)

Except SortField objects don't appear to be marshalled properly across
DRb.

Luckily you can specify the sort field and reverse option as free form
text to the query, but you apparently can't specify the type.

Possible solutions:

 * Maybe you can specify the type. Does anyone know how?

 * Maybe SortField can be made to marshall. Does anyone know how, or
where best to start adding this if necessary?

 * Maybe we can add this support to Ferret.  Doesn't anyone have any
clues where to start? We don't mind doing some C coding :)

Thanks in advance!

John.

Hi!

Do you use aaf? In this case it should work (tm), since aaf has  
support for this built in, see

http://projects.jkraemer.net/acts_as_ferret/browser/trunk/plugin/acts_as_ferret/lib/ferret_extensions.rb

If not, feel free to take the marshalling code to monkey patch your  
Ferret - no C coding necessary ;)

Cheers,
Jens

Hi John

I just tried it (ORing the words) again with some real records to give 
you an example, and it worked, embarrassingly (for me).  It's that 
verdammt observer effect, when something start working the moment you 
get someone else to look at it.

I guess i had some kind of brainwrong when trying it earlier.

thanks a lot anyway
max

We certainly do use aaf.  I'll take a look why this isn't working for
us.

Thanks Jens, you're awesome as always :)

Hello, I have just come across the same situation at our index.

Search for:
black house
(without quotes) and several items with multiple occurrence of 'black'  
but without any 'house' come before items with one occurrence of  
'black' and one 'house'.

It seems that ferret ranks higher items with multiple single term  
occurrences than items which have all terms but each term only once.  
Is this true? How could this be changed, without changing query - some  
indexing option maybe?

Subject: [Ferret-talk] using tokenizers ?
Message-ID: <60d886530809280320n1659a6c4pa63e2480a26dd882@mail.gmail.com>

Hi lis

I using Ferret to index some files for a specific usage.

I want to know how can I set a tokenizer for some of my index fields and if
I can choose a different tokenizer for each field. For example:

If in my document I have two fields :F1 and :F2. What I have to do if I want
that the field :F1 will be tokenized with a StandardTokenizer and :F2  with
the WhiteSpaceTokenizer??

thank you
