Hi all,
I am building a searchinterface where the user looks for product
descriptions that fit his or her specs. One potential specs is for
instance length. The product description holds two fields:
length_from = 1
and
length_to = 10
If the query value is 5 the search should be succesful. Here
Not sure that I get everything:
In the framework that we have built we use a 'simple' object mapping
that connects a database table with an object and implicetely with a
cache. It is build on top of JDBC.
The key fields of the database are used to create a DbKey element a
simple array of
In my Clipper days I could build an index on English words using a
technique that was called soundex. Searching in that index resulted in
hits of words that sounded the same. From what i remember this technique
only worked for English. Has it ever been generalized?
What i am trying to solve is

Do you have the url? The sources are off course very welcome as well.

Thanks for the reference to Metaphone et al. This is the direction I am
looking for. What I don't get is why so much of the 'knowledge' of these
algoritms is stored in the 'process'. I guess it has to be performance.

Aad,
Are you trying to check the spelling of English words by Dutch children?
Uh no, I am trying to correct the spelling of Dutch words by Dutch
children who, as most children do, make phonetic spelling mistakes.
Yep,
This is how we do it.
We have a search.xml that maps database fields to search fields and a
parameter part that describes the 'click for detailed result url' and
the parameter names (based on the search fields). In this xml we also
describe how the different fields should be stored we have
If that is a general thought then I will plan for some time to put this
in action.

Nice, very similar to what I was thinking of, where the most
significant difference is probably just that I was thinking of a batch
indexer, not one embedded in a web container.
Nope,
it is very possible. We have an index that holds the search info for
documents, messages in discussion threads, filled in forms etc. etc.
each having their own structure.

How do you kick off your reindex? Could it be a session timeout?

We are doing similar stuff. We actually do create a hash of database
name, table name and id to form a unique id. So far I have not had any
problems with it.

Steve,
The behavior that you descibe is as expected. I have tackled a similar
problem to yours by creating a proxy object that acts as a gatekeeper to
all IndexReader, IndexSearcher and IndexWriter operations. With fully
synchronized access to all methods of the proxy you will not run into

where the lock came from? e.g a timestamp as part of the filename?

Hi,
From earlier postings I understand that when lucene opens an
IndexWriter or executes a number of specific methods on an IndexReader
that a lock
is created in .../tomcat/temp. My question is. Are these files ever
deleted after something has gone wrong
when I open a writer?
2. can I have one or multiple readers open when I open a writer?
And if not. I am writing an application that does regular updates on the
index what kind of strategy could you advise? Should I use
ResourcePooling at all?
TIA,

Also,
You can also use an alternative spellchecker for the 'checking part' and
use the Ngram algorithm for the 'suggestion' part. Only if the spell
'check' declares a word illegal the 'suggestion' part would perform its
magic.
