30.3. New Geometric
Search Index - Settings geomsearch.cfg
In order to
improve the performance at the GeoSearch and Topology Search, the structure
of the Geo Index has been completely revised. See Section 1.7.5.8.10.2, “Caching /
geometric search index as of V9.08” in PARTsolutions - Administration Manual. There you can find information on the
following points:
New
structure of indices
General
settings under $CADENAS_SETUP/geomsearch.cfg
Migration of
indices
After a
software update to version 9.08 the existing geometric search index is
reused. If you want to profit from the new search index as of version
9.08 (significantly faster search), then you have to perform an index
conversion via Migration Assistant.
- At catalogs, which already have the new V9V2
index
- At catalogs, which still have the old V9 index
(<= 9.07)
Details on
this are found under Migration.
Different
modes for the generation of indices
Changes at
the actual search
For Geo and
Topo indices there are 3 different modes each for conducting the search,
depending on what was determined under $CADENAS_SETUP/geomsearch.cfg in
the section [settings].
Caching

Access on
Topo values via VBS
Conversion
successively:
Via config

Key
convertindex and converttopoindex: Conversion of old indices into

active. Then the conversion happens automatically, if an old index is
created.
An old
index is created, if createNewDirectly is 0 (see next
point).
Each
access on the GeoIndex (search, generation, ...) uses this
setting.
Key:
createNewDirectly
Control
whether an old or a new index shall be created.
Each access on the GeoIndex (search,
generation, ...) uses this setting.
Possible values:
0:
Create old index
The
"convert" keys are also relevant, if no old index is available, but
has to created first.
1:
Create new
index
That
means that with each action creating an index, always the new index
is created.

found under Section 1.7.5.8, “
geomsearch.cfg
” in PARTsolutions - Administration Manual.
