The University of California Berkeley Library recommends a second opinion when searching the Internet, and Exalead is one of its top recommendations.

The search engine features a number of advanced options including phonetic search for those who are sometimes spelling challenged. Spell a word like it sounds and results will include words that sound like what was typed into the search field.There is also a proximity search feature with a "Near" operator that finds documents where the query terms are within 16 words of each other, and a "Next" operator where search terms are next to each other. Other options include searching in a specific language only, after or before a certain date, and a prefix search that looks for the beginning letters of a word.In the results, users see thumbnail pictures of Web pages, which can be pulled up and previewed without leaving the site.In addition, Exalead has enterprise search products available (desktop, network). Its Cloudview platform support 300 formats, including structured data (RDBMS, ERP, Lotus Notes, directories) and unstructured content (e-mail messages, PDFs, Office documents, Web pages).

Social networking meets social searching. Users can offer feedback on results of their search queries, which are tabulated from across the three top search engines (Google, Yahoo, Bing). The feedback moves individual results either up or down in the rankings, which is designed to make the results more relevant as time goes on. Users also can create custom algorithm, which lets them determine how results will be ranked.
