N2 Lexica
N2 Lexica is a simple and easy to use content management system for electronic documents like TIFF images, Adobe PDF, HTML, XML and Microsoft office documents such as Word, PowerPoint and Excel. It is capable of indexing terabytes of data and performing intelligent searches using a simple syntax.

How N2 Lexica works

  • N2 Lexica can instantly search terabytes of text because it builds a search index that stores the location of each word in a document.
  • Indexing is easy. Simply select folders or entire drives to index and N2 Lexica does the rest.
  • N2 Lexica automatically recognizes and supports all popular file formats and never alters original files.
  • A single index can hold over a terabyte of text (billions of documents).
  • N2 Lexica can also create and search with a single request over an unlimited number of indexes.

Relevancy Ranking:
Documents that match the query are ranked based on the number of occurrence in the document and the number of documents that have the term. In advanced searches it can even rank matches based on the proximity of key words to each other.
