Query Ranking Expressions (QRE)
For each UI, administrators can configure specific ranking rules, based on context and result sets. This can be used to promote content based on profile attributes of the current user, such as locations, history, languages, and roles.
Click-through data and manual document rating are used in relevance calculations. This is automatically shared among colleagues based on security group membership (showing social proximity).
Languages are automatically identified at indexing time, improving content processing and relevance algorithms.
Automatic Query Correction
The spelling of the search queries is checked against the index content in order to suggest proper spelling even for words that are not normally part of general dictionaries (examples: internal project codes, scientific terms, personal names, etc.).
The administrator can create a thesaurus and link it to the query. Thesauruses can be created from scratch or imported from existing lists.
Variations of a keyword, including plural and adjective/noun/verb word endings, are treated as synonyms, to broaden the search when required.
Administrators can assign specific results to appear at the top of the list for specific queries.
