Dear Goetz,

I have the same requirement (patent documents containing text in different languages).

I ended up splitting/filtering each original document in localized parts inserted in different collections (each collection having its own full text index configuration).

BaseX is as flexible as our data !

Best regards,

Objet : [basex-talk] multi-language full-text indexing

I’m working with documents destined to be consumed anywhere in the European Community. Many of them have the same tags multiple times but with a different language attribute. It does not make sense to create a full-text index for the whole of these documents therefore. It is desirable to have documents indexed by locale-specific parts, e.g.

CREATE FULL-TEXT INDEX ON DATABASE XY STARTING WITH (

(path_a)/LOCALIZED_PART_A[@LANG=$lang],

(path_b)/LOCALIZED_PART_B[@LG=$lang],…

) FOR LANGUAGE $lang IN (

BG,

DN,

DE WITH STOPWORDS filepath_de WITH STEM = YES,

EN WITH STOPWORDS filepath_en,

FR, …

)  [USING language_code_map]

and then to write full-text retrieval queries with a clause such as ‘FOR LANGUAGE BG’, for example. The index parts would be much smaller and full-text retrieval therefore much faster. The language codes would be mapped somehow to standard values recognized by BaseX in the language_code_map file.

Are there any efforts towards such a feature?
