Ok so it is not possible to store other part of information in the index
? like part-of-speach ?
Thanks for the fast answer

Hi,
The type attribute is not stored in index. The main intention behind this
attribute is to use it inside the analysis chain. E.g. you have some
tokenizer/stemmer/whatever that sets the attribute. The last TokenFilter before
indexing may then change the term accordingly (e.g. adding the type as a
payload, or append it to the term itsself) to get the information into index -
but this is mainly your task. The same applies for other language specific
attributes (like Japanese ones). The keyword attribute is another example, it
is also not indexed, but is solely used to control behavior of later
TokenFilters (e.g. prevent stemming).

Subject: Lucene TypeAttribute not used during querying
Hello,
I wonder why the TypeAttribute is not used for queries ?
It seems that it is used only during analysis.
Why it is not used in org.apache.lucene.index.Term ?
