Oracle Text Makes Search Scores Adjustable
July 29, 2012
They explain the process in laymen’s terms as:
“In theory, the more relevant the search term is to the document, the higher ranked Score it should receive. But in practice, the relevancy score can seem somewhat of a mystery. It’s not entirely clear how it ranks the importance of some documents over others based on the search term. And often times, once a word appears a certain number of times within a document, the Score simply maxes out at 100 and the top results can be difficult to discern from one another.”
To index, search and analyze text both in the Oracle database and on the web, Oracle Text uses standard SQL. This software is capable of utilizing keyword search, context queries, Boolean operations, mixed thematic queries, HTML/XML and more.
It can also perform linguistic analysis and support multiple languages with their advanced relevance ranking technology. There are additional features available for those who need even more advanced search methods like clustering and classification.
Oracle has been a leader in database software for more than three and a half decades. Their knowledge on adjusting search results should not come as a shock. Oracle is one company that will probably remain on top with enterprise grade applications and platform services.
