Hi,
I see from Karstens reply () to an earlier discussion that a pure "search" index disables classification, similarity searching, similar terms and "etc".
So I guess that the "classification" type index activates the services:
- classification
- similarity searching
- similar terms
What services are "etc", and what services does the "search" index activate? Is there a document explaining this, and what the different services does?
Basically: What services does the "search" index activate/utilize and what services does the "classification" index activate/utilize, and a description of the services.
Best regards,
Bjorn
Hi Bjorn,
the "etc." points to anything that could also be based on the text-mining engine of TREX. Anything that works with text similarities and/or statistic associations of terms.
In the TREX INdex Server there are three sub-engines:
- The Indexing Engine that builds up search indices and performs any pure searches over document content (including fuzzy and lingusitic)
- The Text-Mining Engine that builds up a multidimensional vector space from all indexed terms and documents. It determines document similarities, extracts related terms and does example-based classification. It is disabled (including the query-based classification, although that is not based on the vector engine) when chosing a pure search index.
- The Attribute Engine that indexes and searches over KM properties and is also heavily used in other (not KM), table-data-focused scenarios that use TREX.
You can find a presentation that may illustrate this here post under:

<b>NOTE:</b>
Not all TREX technical abilities that are described here are fully available in KM.
Regards, Karsten
