SOLR Relevancy Tuning from Search Technologies
February 11, 2013
Search Technologies introduced “Solr Lucene Relevancy Tuning.” Search Technologies will supply services to improve the relevancy of results within an existing Solr/Lucene implementation. If the service works as advertised, this could be a boon to many organizations awash with extraneous data. The announcement explains:
This engagement will provide powerful relevancy ranking improvements in an existing Solr installation. This includes setting up a basic system for relevancy evaluation, based on a set of sample queries, so that improvements can be quantitatively measured. Additions to the default relevancy formula in Solr Lucene can dramatically improve search results, solving many of the most thorny relevancy problems including:
- Reducing the impact of peripheral content (sidebars, ads, tangential discussions, etc.)
- Automatically handling word phrases in a flexible manner, reducing the need to use complex query constructions to obtain good search results.”
The Search Technologies’ solution changes the default Solr/Lucene functionality, which can overemphasize document size and term frequency. Search Technologies’ new Parameterized Document Similarity Function provides more control over these formulas through configurable parameters. The company’s Gradient Proximity Boost operator eliminates the need to tweak Solr/Lucene’s default “hard window,” the term-proximity parameters which can trigger a document boost. The method does this by measuring the density and completeness of terms across each document, gradually boosting documents in which terms cluster.
The post identifies the expected engagement tasks and deliverables associated with this software. The only pre-requisite listed is the presence of a working Solr /Lucene system with already-indexed documents. The firm promises ongoing maintenance and support services, including an optional round-the-clock support package.
Founded in 2005, Search Technologies bills themselves as the largest (independent) IT services company dedicated to search-engine implementation, consulting, and managed services. Staffed with veterans of the search field, the company prides itself on innovation. Search Technologies is headquartered in Herndon, Virginia, and maintains two other U.S. offices as well as locations in Berkshire, U.K., and San Jose, Costa Rica.
