ZCatalog - Indexes: Manage Catalog Indexes
Description
This view allows you to manage the catalog indexes.
The catalog provides searching by indexing information about
cataloged objects. Indexes record information about object
attributes.
Controls
-
[List of Indexes]
- Each line contains one Index entry. The
checkbox in the front allows you to mark an index for
deletion. Next the Index name is listed which corresponds to
attribute names of various objects.
-
Delete
- The checkmarked Index(es) will be deleted.
-
Add Index
- Name
- Allows you to enter the name of a new
index.
-
[Type of Index]
- You have the choice between four types of
Indexes, called
TextIndex
, FieldIndex
, KeywordIndex
and
PathIndex
. Please refer to the table below to see a
description of each Index.
-
Add
- The new Index will be added to this catalog.
This table lists the different Index types and describes their
purpose.
-
TextIndex
- TextIndexes break content up into individual
words. These indexes are often refered to as full-text
indexes. Text indexes sort results by score, meaning they
return
hits
in order from the most relevant to the lest
relevant.
-
FieldIndex
- FieldIndexes treat the value of an objects
attribute atomically, and can be used, for example, to track
only a certain subset of object values, such as
meta_type
.
-
KeywordIndex
- KeywordIndexes index a sequence of objects
that act as
keywords
for an object. A Keyword Index will
return any objects that have one or more keywords specified in
a search query.
-
PathIndex
- Index the physical path of a sequence of
objects. A Path Index will return all objects that match a
partitial path specified in a search query.
-
TopicIndex
- A TopicIndex is a container for so-called
FilteredSet. A FilteredSet consists of an expression and a set
of internal ZCatalog document identifiers that represent a
pre-calculated result list for performance reasons. Instead of
executing the same query on a ZCatalog multiple times it is much
faster to use a TopicIndex instead.
