MnoGoSearch for Windows is a useful search engine that was designed to organize search within a website, number of websites, intranet or local system.

To search through documents you have to index them first using the indexer component of mnoGoSearch.

Indexer is a spider that reads the documents you specify and
stores information about words it finds in tables in a built-in database.

You can specify what kind (format) of documents to index, location of documents (a website, a directory on server, single webpage, etc.).

You can define the level of importance (weight) of various document properties and parts that are taken into account during searching.
