- /** Returns the number of documents containing the term <code>t</code>.
+ /** Returns the number of documents, including deleted, containing the
term <code>t</code>.
there is a note about this in the javadocs for deleteDocument, but i agree
it's not entirely clear ...
unless i'm mistaken, docFreq isn't the only method affected by deleted
docs, things like termDocs, termPositions, terms, ... pretty much all of
hte IndexReader methods work that way (even getFieldNames could be
missleading if the only doc with a field of that name has been deleted)
rather then putting a specifc note about it in in each method, it might
make more sense to elaborate on this in the class level docs, and then
note only the exceptions (document(int) is hte only one i can think of ...
it throws an exception)
I understand why, but wonder wether or not this feature is actually used by
something, if I need to mimic the behaviour in LUCENE-550 in order to ensure
compabillity?
I don't know if i'd consider it a "feature" ... i think of it more as an
caveat that lucene makes in order be able to optimize some things ... i
don't think it's neccessary that alternate impls mimic this behavior
exactly.
