I am assuming that the code you provided goes into a
manage_addCustomIndex method that is part of a CustomIndex
Python Product.
hehehehe, nothing so general-purpose as that ;-)
You will need to implement a subclass derived from one of
the standard
indexes to provide your custom indexing policy, whatever that is.
Can you provide the code for your custom KeywordIndex, so I
have a starting point? I realize yours subclasses a
KeywordIndex, and I probably need to subclass a TextIndex,
but it would still probably help. I can integrate and hack
on other peoples code better than I can write my own from
scratch.
from SearchIndex.UnKeywordIndex import UnKeywordIndex, MV, intSet
from types import ListType, TupleType
class UnTrackingIndex(UnKeywordIndex):
meta_type = 'Tracking Properties Index'
"""Like a Keyword Index, only it indexes tracking properties
"""
def __init__(self,question):
id = 'tracking_'+unicode(question).encode('unicode-escape')
self.question = question
UnKeywordIndex.__init__(self,id)
def index_object(self, i, obj, threshold=None):
""" index an object 'obj' with integer id 'i'"""
index = self._index
unindex = self._unindex
try:
kws = obj.tracking_answers(self.question)
if type(kws) not in [type([]),type(())]:
raise ValueError('Indexing a tracking property set of
inappropriate type %r' % type(kws))
except:
kws = (MV,)
# index each item in the sequence
for kw in kws:
set = index.get(kw)
if set is None:
index[kw] = set = intSet()
set.insert(i)
unindex[i] = tuple(kws)
self._index = index
self._unindex = unindex
return 1
