Hello,
Create Term from field name and emty valu
Call read->terms( Term * ) to get term enum
Use TermDocs together with TermEnum to get related document ids
RangeQuery::rewrite(IndexReader* reader) could be a good example I think
This way is very efficient, but you should not read other document field values
inside this cycle
Regards
Borek

Subject: [CLucene-dev] Retrieve all values for a given field ?
Hello, me again, with yet another CLucene question !
I would like to retrieve (in a relatively fast way) all the values for a given
field. For example, if my index looks like :
Document1 ( fieldName=value1 )
Document2 (fieldName=value1 )
Document3 (fieldName=value2 )
Document4 (fieldName=value2 )
I'd like to be able to call something like getFieldValues( "fieldName" ) and
get a list ( value1, value2 ) in return.
How can I do that ?
Thanks in advance
