Lucene Dictionary

[ineb]

Hello,

is the Lucene Dictionary-Feature and the Stem-Filter supported and implemented by Alfresco?

And is it possible to define User-Dictionaries? It should be possible to enter the word "car" and Alfresco searches automatically with the User-Dictionary also for "vehicule".


Backgrounds:
I have to manage a lot of Documents scanned from OCR, some with lots of spelling mistakes. That's why I need a Stem-Filter.

Hi

You can configure whatever analyzer you want. By default the language specific set from lucene 2.0 are available. The stemming analyzers can be used as required and are the default for some languages.

There is no in-built thesaurus. This can be done as part of analysis. So you can write your own analyzer to do this (see the book Lucene in Action). At the moment we use the same analyzer at both index and seach time - so the synonym list will be in the index and the search. This is on my list to resolve.

Synonym expansion would also need to be locale specific for the general case.

Cheers
