Hi Andi,
Thanks to your hints I was now able to build PyLucene4.1 and got further with
the FacetExample.py - The imports should be OK now and most of the required
changes are done I guess. However I now reached another problem: I need to
instantiate the class 'FacetsCollector' but get an error when doing so:
File "samples/FacetExample.py", line 222, in searchWithRequestAndQuery
facetsCollector = FacetsCollector(facetSearchParams, indexReader,
taxoReader)
NotImplementedError: ('instantiating java class', <type 'FacetsCollector'>)
The java example has this line:
FacetsCollector facetsCollector = new FacetsCollector(facetSearchParams,
indexReader, taxoReader);
and javadocs state it has a public constructor:
http://lucene.apache.org/core/4_1_0/facet/org/apache/lucene/facet/search/FacetsCollector.html#FacetsCollector(org.apache.lucene.facet.search.params.FacetSearchParams,%20org.apache.lucene.index.IndexReader,%20org.apache.lucene.facet.taxonomy.TaxonomyReader)
So what could be the reason for this behavior?
I have another problem with the constructor of FacetSearchParams: it is
expecting arguments:
(List<FacetRequest> facetRequests, FacetIndexingParams indexingParams)
but neither
FacetSearchParams(Arrays.asList([facetRequest,]), indexingParams)
nor
FacetSearchParams([facetRequest,], indexingParams)
does it here. I get
lucene.InvalidArgsError: (<type 'FacetSearchParams'>, '__init__', (<List:
[root/a nRes=10 nLbl=10]>, <FacetIndexingParams:
org.apache.lucene.facet.params.FacetIndexingParams@f97ad3c0>))
I thought that JavaList could help, but I cannot import it:
>>> from lucene.collections import JavaList
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Users/koch/.virtualenvs/pylucene/lib/python2.7/site-packages/lucene-4.1-py2.7-macosx-10.8-x86_64.egg/lucene/collections.py",
line 17, in <module>
from org.apache.pylucene.util import \
ImportError: No module named pylucene.util
>>>
That's probably because I had to disable in Makefile
## JARS+=$(HIGHLIGHTER_JAR) # needs memory contrib
## JARS+=$(EXTENSIONS_JAR) # needs highlighter contrib
Do you think that's a type cast issue and that JavaList would help here?
I need to define a 'typed' list , e.g. List<FacetRequest>

Any hints?

Thomas
