- new index type - new index type
Changes to TextIndex:
- ZMI allows to select a different vocabulary. To use a vocabulary different
from the ZCatalogs default vocabulary 'Vocabulary' you must create a new
Vocabulary through the ZMI of the ZCatalog. After creating the vocabulary you
can choose the vocabulary on the ZMI management screen for the text index.
- the default operator might be overridden by specifying a new one
as 'operator' (see below)
- removed direct dependency from Splitter module. Splitter is now
acquired from used vocabulary
- usage of the 'textindex_operator' is deprecated
- lots of internal rework
Changes to Vocabulary:
- added Splitter selection on the add formular
Changes to ZCatalog Changes to ZCatalog
- Vocabulary.py moved to Products/PluginIndexes/TextIndex. A wrapper
for backward compatibility is in place
- added ZCatalogIndexes.py to provide access to indexes with pluggable - added ZCatalogIndexes.py to provide access to indexes with pluggable

'_inverseLex' -- Contains the mapping from word_id => word
'_digrams' -- Contains a mapping from digram => word_id
Before going further, it is necessary to understand what a digram is,
as it is a core component of the structure of this lexicon. A digram
is a two-letter sequence in a word. For example, the word 'zope'
would be converted into the digrams::
['$z', 'zo', 'op', 'pe', 'e$']
where the '$' is a word marker. It is used at the beginning and end
of the words. Those digrams are significant.

ZCatalog - searchResults: specifying parameters for a search query
The searchResults() method of the ZCatalog accepts parameters that
define a query to be made on that catalog. A query can either be
passed as keyword argument to searchResults(), as a mapping, or as
part of a Zope REQUEST object, typically from HTML forms.
The index of the catalog to query is either the name of the
keyword argument, a key in a mapping, or an attribute of a record
object.
Attributes of record objects
'query' -- either a sequence of objects or a single value to be
passed as query to the index (mandatory)
'operator' -- specifies the combination of search results when
query is a sequence of values. (optional, default: 'or').
Allowed values:
'and', 'or', 'andnot', 'near'

There is a ZCatalog UML model that sheds some light on what is
going on here. '_index' is a BTree which maps word ids to mapping
from document id to score. Something like:
{'bob' : {1 : 5, 2 : 3, 42 : 9}}
{'uncle' : {1 : 1}}
The '_unindex' attribute is a mapping from document id to word
ids. This mapping allows the catalog to unindex an object:
{42 : ('bob', 'is', 'your', 'uncle')
This isn't exactly how things are represented in memory, many
optimizations happen along the way.
