As part of the development of Minerazzi, we have published an article explaining two of our search modes: XOR and XNOR. Additional articles explaining other modes will soon follow.

We believe that IR and SEO practitioners will find these search modes particularly useful.

The beauty of XOR and XNOR searches is that these allow users to run complex co-occurrence searches in a straightforward manner. This is important as Latent Semantic Indexing information is related to term-term co-occurrence relationships.
