Unparalleled Intelligent Searching

Provides API access to over twenty five precision search options:

  • Search options include synonym/concept/thesaurus, fuzziness adjustable from 0 to 10, Boolean, phrase, wildcard, proximity, stemming, numeric range, regular expressions, natural language relevancy-ranked by hit density and rarity, and variable term weighting.
  • Search options can be used alone or in almost any combination (regardless of complexity).
  • Uses proprietary indexing and searching algorithms engineered for scalability.
  • Indexed search time is generally less than a second.
  • Indexing is optimised to maintain consistent speed over even the largest document collections. Over 1Tbyte of data per index.
