OK, I added JavaSet to my codebase.
You can now use the one in the PyLucene's collections module:
>>> from lucene.collections import JavaSet
But still no joy -- I can now call
mlt = MoreLikeThis(...)
mlt.setStopWords(JavaSet(set(["foo", "bar", "bletch"])))
terms = mlt.retrieveInterestingTerms(...)
Unfortunately, I still get "foo", "bar", and "bletch" in the terms.
So something is still off. Looking at the code for use of stopwords in
MLT, it's pretty simple and looks correct.
Well, that might be a different issue altogether. I believe PyLucene comes
with a sample illustrating MoreLikeThis functionality (in the Lucene in
Action sample set). Maybe there are hints there as to what might be wrong.
I verified that a JavaSet instance is a valid java.util.Set:
>>> from lucene import *
>>> from lucene.collections import JavaSet
>>> initVM(CLASSPATH)
>>> a = JavaSet(set(['foo', 'bar', 'baz']))
>>> b = HashSet(a)
>>> a
<JavaSet: org.apache.pylucene.util.python...@cd4544>
>>> b
<HashSet: [foo, baz, bar]>
>>> list(a)
['baz', 'foo', 'bar']
You can also now make a HashSet via Arrays:
>>> HashSet(Arrays.asList(JArray('string')(('foo', 'bar', 'baz'))))
<HashSet: [foo, baz, bar]>
Andi..
